| CVE-2018-18559 | 2 Linux, Redhat | 16 Linux Kernel, Enterprise Linux, Enterprise Linux Desktop and 13 more | 2024-11-21 | 8.1 High |
| In the Linux kernel through 4.19, a use-after-free can occur due to a race condition between fanout_add from setsockopt and bind on an AF_PACKET socket. This issue exists because of the 15fe076edea787807a7cdc168df832544b58eba6 incomplete fix for a race condition. The code mishandles a certain multithreaded case involving a packet_do_bind unregister action followed by a packet_notifier register action. Later, packet_release operates on only one of the two applicable linked lists. The attacker can achieve Program Counter control. | ||||
| CVE-2018-18397 | 3 Canonical, Linux, Redhat | 12 Ubuntu Linux, Linux Kernel, Enterprise Linux and 9 more | 2024-11-21 | N/A |
| The userfaultfd implementation in the Linux kernel before 4.19.7 mishandles access control for certain UFFDIO_ ioctl calls, as demonstrated by allowing local users to write data into holes in a tmpfs file (if the user has read-only access to that file, and that file contains holes), related to fs/userfaultfd.c and mm/userfaultfd.c. | ||||
| CVE-2018-18311 | 8 Apple, Canonical, Debian and 5 more | 23 Mac Os X, Ubuntu Linux, Debian Linux and 20 more | 2024-11-21 | N/A |
| Perl before 5.26.3 and 5.28.x before 5.28.1 has a buffer overflow via a crafted regular expression that triggers invalid write operations. | ||||
| CVE-2018-18281 | 4 Canonical, Debian, Linux and 1 more | 10 Ubuntu Linux, Debian Linux, Linux Kernel and 7 more | 2024-11-21 | N/A |
| Since Linux kernel version 3.2, the mremap() syscall performs TLB flushes after dropping pagetable locks. If a syscall such as ftruncate() removes entries from the pagetables of a task that is in the middle of mremap(), a stale TLB entry can remain for a short time that permits access to a physical page after it has been released back to the page allocator and reused. This is fixed in the following kernel versions: 4.9.135, 4.14.78, 4.18.16, 4.19. | ||||
| CVE-2018-16884 | 4 Canonical, Debian, Linux and 1 more | 8 Ubuntu Linux, Debian Linux, Linux Kernel and 5 more | 2024-11-21 | 8.0 High |
| A flaw was found in the Linux kernel's NFS41+ subsystem. NFS41+ shares mounted in different network namespaces at the same time can make bc_svc_process() use wrong back-channel IDs and cause a use-after-free vulnerability. Thus a malicious container user can cause a host kernel memory corruption and a system panic. Due to the nature of the flaw, privilege escalation cannot be fully ruled out. | ||||
| CVE-2018-16871 | 3 Linux, Netapp, Redhat | 31 Linux Kernel, Cloud Backup, H300e and 28 more | 2024-11-21 | 7.5 High |
| A flaw was found in the Linux kernel's NFS implementation, all versions 3.x and all versions 4.x up to 4.20. An attacker, who is able to mount an exported NFS filesystem, is able to trigger a null pointer dereference by using an invalid NFS sequence. This can panic the machine and deny access to the NFS server. Any outstanding disk writes to the NFS server will be lost. | ||||
| CVE-2018-16402 | 5 Canonical, Debian, Elfutils Project and 2 more | 10 Ubuntu Linux, Debian Linux, Elfutils and 7 more | 2024-11-21 | 9.8 Critical |
| libelf/elf_end.c in elfutils 0.173 allows remote attackers to cause a denial of service (double free and application crash) or possibly have unspecified other impact because it tries to decompress twice. | ||||
| CVE-2018-16396 | 4 Canonical, Debian, Redhat and 1 more | 9 Ubuntu Linux, Debian Linux, Enterprise Linux and 6 more | 2024-11-21 | N/A |
| An issue was discovered in Ruby before 2.3.8, 2.4.x before 2.4.5, 2.5.x before 2.5.2, and 2.6.x before 2.6.0-preview3. It does not taint strings that result from unpacking tainted strings with some formats. | ||||
| CVE-2018-16395 | 4 Canonical, Debian, Redhat and 1 more | 7 Ubuntu Linux, Debian Linux, Enterprise Linux and 4 more | 2024-11-21 | N/A |
| An issue was discovered in the OpenSSL library in Ruby before 2.3.8, 2.4.x before 2.4.5, 2.5.x before 2.5.2, and 2.6.x before 2.6.0-preview3. When two OpenSSL::X509::Name objects are compared using ==, depending on the ordering, non-equal objects may return true. When the first argument is one character longer than the second, or the second argument contains a character that is one less than a character in the same position of the first argument, the result of == will be true. This could be leveraged to create an illegitimate certificate that may be accepted as legitimate and then used in signing or encryption operations. | ||||
| CVE-2018-14648 | 3 Debian, Fedoraproject, Redhat | 4 Debian Linux, 389 Directory Server, Enterprise Linux and 1 more | 2024-11-21 | N/A |
| A flaw was found in 389 Directory Server. A specially crafted search query could lead to excessive CPU consumption in the do_search() function. An unauthenticated attacker could use this flaw to provoke a denial of service. | ||||
| CVE-2018-14647 | 6 Canonical, Debian, Fedoraproject and 3 more | 15 Ubuntu Linux, Debian Linux, Fedora and 12 more | 2024-11-21 | 7.5 High |
| Python's elementtree C accelerator failed to initialise Expat's hash salt during initialization. This could make it easy to conduct denial of service attacks against Expat by constructing an XML document that would cause pathological hash collisions in Expat's internal data structures, consuming large amounts CPU and RAM. The vulnerability exists in Python versions 3.7.0, 3.6.0 through 3.6.6, 3.5.0 through 3.5.6, 3.4.0 through 3.4.9, 2.7.0 through 2.7.15. | ||||
| CVE-2018-14646 | 2 Linux, Redhat | 10 Linux Kernel, Enterprise Linux, Enterprise Linux Desktop and 7 more | 2024-11-21 | N/A |
| The Linux kernel before 4.15-rc8 was found to be vulnerable to a NULL pointer dereference bug in the __netlink_ns_capable() function in the net/netlink/af_netlink.c file. A local attacker could exploit this when a net namespace with a netnsid is assigned to cause a kernel panic and a denial of service. | ||||
| CVE-2018-14634 | 4 Canonical, Linux, Netapp and 1 more | 16 Ubuntu Linux, Linux Kernel, Active Iq Performance Analytics Services and 13 more | 2024-11-21 | N/A |
| An integer overflow flaw was found in the Linux kernel's create_elf_tables() function. An unprivileged local user with access to SUID (or otherwise privileged) binary could use this flaw to escalate their privileges on the system. Kernel versions 2.6.x, 3.10.x and 4.14.x are believed to be vulnerable. | ||||
| CVE-2018-14633 | 4 Canonical, Debian, Linux and 1 more | 11 Ubuntu Linux, Debian Linux, Linux Kernel and 8 more | 2024-11-21 | 7.0 High |
| A security flaw was found in the chap_server_compute_md5() function in the ISCSI target code in the Linux kernel in a way an authentication request from an ISCSI initiator is processed. An unauthenticated remote attacker can cause a stack buffer overflow and smash up to 17 bytes of the stack. The attack requires the iSCSI target to be enabled on the victim host. Depending on how the target's code was built (i.e. depending on a compiler, compile flags and hardware architecture) an attack may lead to a system crash and thus to a denial-of-service or possibly to a non-authorized access to data exported by an iSCSI target. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is highly unlikely. Kernel versions 4.18.x, 4.14.x and 3.10.x are believed to be vulnerable. | ||||
| CVE-2018-13405 | 6 Canonical, Debian, F5 and 3 more | 34 Ubuntu Linux, Debian Linux, Big-ip Access Policy Manager and 31 more | 2024-11-21 | 7.8 High |
| The inode_init_owner function in fs/inode.c in the Linux kernel through 3.16 allows local users to create files with an unintended group ownership, in a scenario where a directory is SGID to a certain group and is writable by a user who is not a member of that group. Here, the non-member can trigger creation of a plain file whose group ownership is that group. The intended behavior was that the non-member can trigger creation of a directory (but not a plain file) whose group ownership is that group. The non-member can escalate privileges by making the plain file executable and SGID. | ||||
| CVE-2018-12327 | 2 Ntp, Redhat | 3 Ntp, Enterprise Linux, Rhel Eus | 2024-11-21 | N/A |
| Stack-based buffer overflow in ntpq and ntpdc of NTP version 4.2.8p11 allows an attacker to achieve code execution or escalate to higher privileges via a long string as the argument for an IPv4 or IPv6 command-line parameter. NOTE: It is unclear whether there are any common situations in which ntpq or ntpdc is used with a command line from an untrusted source. | ||||
| CVE-2018-12207 | 8 Canonical, Debian, F5 and 5 more | 1541 Ubuntu Linux, Debian Linux, Big-ip Access Policy Manager and 1538 more | 2024-11-21 | 6.5 Medium |
| Improper invalidation for page table updates by a virtual guest operating system for multiple Intel(R) Processors may allow an authenticated user to potentially enable denial of service of the host system via local access. | ||||
| CVE-2018-12130 | 3 Fedoraproject, Intel, Redhat | 13 Fedora, Microarchitectural Fill Buffer Data Sampling, Microarchitectural Fill Buffer Data Sampling Firmware and 10 more | 2024-11-21 | N/A |
