| CVE-2023-6779 | 3 Fedoraproject, Gnu, Redhat | 3 Fedora, Glibc, Enterprise Linux | 2024-11-21 | 8.2 High |
| An off-by-one heap-based buffer overflow was found in the __vsyslog_internal function of the glibc library. This function is called by the syslog and vsyslog functions. This issue occurs when these functions are called with a message bigger than INT_MAX bytes, leading to an incorrect calculation of the buffer size to store the message, resulting in an application crash. This issue affects glibc 2.37 and newer. | ||||
| CVE-2023-4260 | 1 Zephyrproject | 1 Zephyr | 2024-11-21 | 6.3 Medium |
| Potential off-by-one buffer overflow vulnerability in the Zephyr fuse file system. | ||||
| CVE-2023-4259 | 1 Zephyrproject | 1 Zephyr | 2024-11-21 | 7.1 High |

| CVE-2023-46853 | 1 Memcached | 1 Memcached | 2024-11-21 | 9.8 Critical |
| In Memcached before 1.6.22, an off-by-one error exists when processing proxy requests in proxy mode, if \n is used instead of \r\n. | ||||
| CVE-2023-46247 | 1 Vyperlang | 1 Vyper | 2024-11-21 | 7.5 High |
| Vyper is a Pythonic Smart Contract Language for the Ethereum Virtual Machine (EVM). Contracts containing large arrays might underallocate the number of slots they need by 1. Prior to v0.3.8, the calculation to determine how many slots a storage variable needed used `math.ceil(type_.size_in_bytes / 32)`. The intermediate floating point step can produce a rounding error if there are enough bits set in the IEEE-754 mantissa. Roughly speaking, if `type_.size_in_bytes` is large (> 2**46), and slightly less than a power of 2, the calculation can overestimate how many slots are needed by 1. If `type_.size_in_bytes` is slightly more than a power of 2, the calculation can underestimate how many slots are needed by 1. This issue is patched in version 0.3.8. | ||||
| CVE-2023-44444 | 2 Gimp, Redhat | 7 Gimp, Enterprise Linux, Rhel Aus and 4 more | 2024-11-21 | 7.8 High |
| GIMP PSP File Parsing Off-By-One Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of GIMP. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of PSP files. Crafted data in a PSP file can trigger an off-by-one error when calculating a location to write within a heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. . Was ZDI-CAN-22097. | ||||
| CVE-2023-41880 | 1 Bytecodealliance | 1 Wasmtime | 2024-11-21 | 2.2 Low |
| Wasmtime is a standalone runtime for WebAssembly. Wasmtime versions from 10.0.0 to versions 10.02, 11.0.2, and 12.0.1 contain a miscompilation of the WebAssembly `i64x2.shr_s` instruction on x86_64 platforms when the shift amount is a constant value that is larger than 32. Only x86_64 is affected so all other targets are not affected by this. The miscompilation results in the instruction producing an incorrect result, namely the low 32-bits of the second lane of the vector are derived from the low 32-bits of the second lane of the input vector instead of the high 32-bits. The primary impact of this issue is that any WebAssembly program using the `i64x2.shr_s` with a constant shift amount larger than 32 may produce an incorrect result. This issue is not an escape from the WebAssembly sandbox. Execution of WebAssembly guest programs will still behave correctly with respect to memory sandboxing and isolation from the host. Wasmtime considers non-spec-compliant behavior as a security issue nonetheless. This issue was discovered through fuzzing of Wasmtime's code generator Cranelift. Wasmtime versions 10.0.2, 11.0.2, and 12.0.2 are all patched to no longer have this miscompilation. This issue only affects x86_64 hosts and the only workaround is to either scan for this pattern in wasm modules which is nontrivial or to disable the SIMD proposal for WebAssembly. Users prior to 10.0.0 are unaffected by this vulnerability. | ||||
| CVE-2023-38429 | 1 Linux | 1 Linux Kernel | 2024-11-21 | 9.8 Critical |
| An issue was discovered in the Linux kernel before 6.3.4. fs/ksmbd/connection.c in ksmbd has an off-by-one error in memory allocation (because of ksmbd_smb2_check_message) that may lead to out-of-bounds access. | ||||
| CVE-2023-30546 | 1 Contiki-ng | 1 Contiki-ng | 2024-11-21 | 9.8 Critical |
| Contiki-NG is an operating system for Internet of Things devices. An off-by-one error can be triggered in the Antelope database management system in the Contiki-NG operating system in versions 4.8 and prior. The problem exists in the Contiki File System (CFS) backend for the storage of data (file os/storage/antelope/storage-cfs.c). In the functions `storage_get_index` and `storage_put_index`, a buffer for merging two strings is allocated with one byte less than the maximum size of the merged strings, causing subsequent function calls to the cfs_open function to read from memory beyond the buffer size. The vulnerability has been patched in the "develop" branch of Contiki-NG, and is expected to be included in the next release. As a workaround, the problem can be fixed by applying the patch in Contiki-NG pull request #2425. | ||||
| CVE-2023-28858 | 1 Redis | 1 Redis-py | 2024-11-21 | 3.7 Low |
| redis-py before 4.5.3 leaves a connection open after canceling an async Redis command at an inopportune time, and can send response data to the client of an unrelated request in an off-by-one manner. NOTE: this CVE Record was initially created in response to reports about ChatGPT, and 4.3.6, 4.4.3, and 4.5.3 were released (changing the behavior for pipeline operations); however, please see CVE-2023-28859 about addressing data leakage across AsyncIO connections in general. | ||||
| CVE-2023-28709 | 4 Apache, Debian, Netapp and 1 more | 5 Tomcat, Debian Linux, 7-mode Transition Tool and 2 more | 2024-11-21 | 7.5 High |
| The fix for CVE-2023-24998 was incomplete for Apache Tomcat 11.0.0-M2 to 11.0.0-M4, 10.1.5 to 10.1.7, 9.0.71 to 9.0.73 and 8.5.85 to 8.5.87. If non-default HTTP connector settings were used such that the maxParameterCount could be reached using query string parameters and a request was submitted that supplied exactly maxParameterCount parameters in the query string, the limit for uploaded request parts could be bypassed with the potential for a denial of service to occur. | ||||
| CVE-2023-27477 | 1 Bytecodealliance | 2 Cranelift-codegen, Wasmtime | 2024-11-21 | 3.1 Low |
| wasmtime is a fast and secure runtime for WebAssembly. Wasmtime's code generation backend, Cranelift, has a bug on x86_64 platforms for the WebAssembly `i8x16.select` instruction which will produce the wrong results when the same operand is provided to the instruction and some of the selected indices are greater than 16. There is an off-by-one error in the calculation of the mask to the `pshufb` instruction which causes incorrect results to be returned if lanes are selected from the second vector. This codegen bug has been fixed in Wasmtiem 6.0.1, 5.0.1, and 4.0.1. Users are recommended to upgrade to these updated versions. If upgrading is not an option for you at this time, you can avoid this miscompilation by disabling the Wasm simd proposal. Additionally the bug is only present on x86_64 hosts. Other platforms such as AArch64 and s390x are not affected. | ||||
| CVE-2023-0818 | 1 Gpac | 1 Gpac | 2024-11-21 | 5.5 Medium |
| Off-by-one Error in GitHub repository gpac/gpac prior to v2.3.0-DEV. | ||||
| CVE-2022-47517 | 1 Drachtio | 1 Drachtio-server | 2024-11-21 | 7.5 High |
| An issue was discovered in the libsofia-sip fork in drachtio-server before 0.8.19. It allows remote attackers to cause a denial of service (daemon crash) via a crafted UDP message that causes a url_canonize2 heap-based buffer over-read because of an off-by-one error. | ||||
| CVE-2022-41916 | 2 Debian, Heimdal Project | 2 Debian Linux, Heimdal | 2024-11-21 | 5.9 Medium |
| Heimdal is an implementation of ASN.1/DER, PKIX, and Kerberos. Versions prior to 7.7.1 are vulnerable to a denial of service vulnerability in Heimdal's PKI certificate validation library, affecting the KDC (via PKINIT) and kinit (via PKINIT), as well as any third-party applications using Heimdal's libhx509. Users should upgrade to Heimdal 7.7.1 or 7.8. There are no known workarounds for this issue. | ||||
| CVE-2022-3872 | 1 Qemu | 1 Qemu | 2024-11-21 | 8.6 High |
| An off-by-one read/write issue was found in the SDHCI device of QEMU. It occurs when reading/writing the Buffer Data Port Register in sdhci_read_dataport and sdhci_write_dataport, respectively, if data_count == block_size. A malicious guest could use this flaw to crash the QEMU process on the host, resulting in a denial of service condition. | ||||
| CVE-2022-3821 | 3 Fedoraproject, Redhat, Systemd Project | 4 Fedora, Enterprise Linux, Rhel Eus and 1 more | 2024-11-21 | 5.5 Medium |
| An off-by-one Error issue was discovered in Systemd in format_timespan() function of time-util.c. An attacker could supply specific values for time and accuracy that leads to buffer overrun in format_timespan(), leading to a Denial of Service. | ||||
| CVE-2022-3786 | 4 Fedoraproject, Nodejs, Openssl and 1 more | 4 Fedora, Node.js, Openssl and 1 more | 2024-11-21 | 7.5 High |
| A buffer overrun can be triggered in X.509 certificate verification, specifically in name constraint checking. Note that this occurs after certificate chain signature verification and requires either a CA to have signed a malicious certificate or for an application to continue certificate verification despite failure to construct a path to a trusted issuer. An attacker can craft a malicious email address in a certificate to overflow an arbitrary number of bytes containing the `.' character (decimal 46) on the stack. This buffer overflow could result in a crash (causing a denial of service). In a TLS client, this can be triggered by connecting to a malicious server. In a TLS server, this can be triggered if the server requests client authentication and a malicious client connects. | ||||
| CVE-2022-3103 | 1 Linux | 1 Linux Kernel | 2024-11-21 | 7.8 High |
| off-by-one in io_uring module. | ||||
| CVE-2022-39274 | 1 Semtech | 1 Loramac-node | 2024-11-21 | 7.5 High |
| LoRaMac-node is a reference implementation and documentation of a LoRa network node. Versions of LoRaMac-node prior to 4.7.0 are vulnerable to a buffer overflow. Improper size validation of the incoming radio frames can lead to an 65280-byte out-of-bounds write. The function `ProcessRadioRxDone` implicitly expects incoming radio frames to have at least a payload of one byte or more. An empty payload leads to a 1-byte out-of-bounds read of user controlled content when the payload buffer is reused. This allows an attacker to craft a FRAME_TYPE_PROPRIETARY frame with size -1 which results in an 65280-byte out-of-bounds memcopy likely with partially controlled attacker data. Corrupting a large part if the data section is likely to cause a DoS. If the large out-of-bounds write does not immediately crash the attacker may gain control over the execution due to now controlling large parts of the data section. Users are advised to upgrade either by updating their package or by manually applying the patch commit `e851b079`. | ||||
