CVE-2026-6238 3 Gnu, Redhat, The Gnu C Library 3 Glibc, Hummingbird, Glibc 2026-06-19 6.5 Medium
The deprecated functions ns_printrrf, ns_printrr and fp_nquery in the GNU C Library version 2.0.1 to version 2.43 fail to validate the RDATA content against the RDATA length in a DNS response when processing A6, CERT, LOC, TKEY or TSIG records, which may allow an attacker to craft a DNS response, causing a target application to crash or read uninitialized memory. These functions are for application debugging only and hence not in the path of code executed by the DNS resolver. Further, they have been deprecated since version 2.34 and should not be used by any new applications. Applications should consider porting away from these interfaces since they may be removed in future versions.
CVE-2026-32746 1 Gnu 1 Inetutils 2026-06-18 9.8 Critical
telnetd in GNU inetutils through 2.7 allows an out-of-bounds write in the LINEMODE SLC (Set Local Characters) suboption handler because add_slc does not check whether the buffer is full.
CVE-2026-24061 2 Debian, Gnu 2 Debian Linux, Inetutils 2026-06-17 9.8 Critical
telnetd in GNU Inetutils through 2.7 allows remote authentication bypass via a "-f root" value for the USER environment variable.
CVE-2026-5419 2 Gnu, Redhat 8 Gnutls, Enterprise Linux, Enterprise Linux Eus and 5 more 2026-06-17 3.7 Low
A flaw was found in gnutls. The PKCS#7 padding check, performed during decryption, was not constant-time. This timing side-channel could allow a remote attacker to potentially leak sensitive information about the padding bytes through observable timing differences. This vulnerability is a form of information disclosure.
CVE-2026-3832 2 Gnu, Redhat 8 Gnutls, Enterprise Linux, Enterprise Linux Eus and 5 more 2026-06-17 3.7 Low
A flaw was found in gnutls. A remote attacker could exploit this vulnerability by presenting a specially crafted Online Certificate Status Protocol (OCSP) response during a TLS handshake. Due to a logic error in how gnutls processes multi-record OCSP responses, a client with OCSP verification enabled may incorrectly accept a revoked server certificate, potentially leading to a compromise of trust.
CVE-2026-42013 2 Gnu, Redhat 8 Gnutls, Enterprise Linux, Enterprise Linux Eus and 5 more 2026-06-17 8.2 High
A flaw was found in gnutls. When validating certificates, an oversized Subject Alternative Name (SAN) could cause the validation process to incorrectly fall back to checking the Common Name (CN) field. This could allow a remote attacker to bypass proper certificate validation, potentially leading to spoofing or man-in-the-middle attacks.
CVE-2026-42012 2 Gnu, Redhat 8 Gnutls, Enterprise Linux, Enterprise Linux Eus and 5 more 2026-06-17 7.1 High
A flaw was found in gnutls. A remote attacker could exploit this vulnerability by presenting a specially crafted certificate that contains Uniform Resource Identifier (URI) or Service (SRV) Subject Alternative Names (SANs). This could cause the certificate validation process to incorrectly fall back to checking DNS hostnames against the Common Name (CN), potentially allowing the attacker to spoof legitimate services or intercept sensitive information.
CVE-2026-5260 2 Gnu, Redhat 8 Gnutls, Enterprise Linux, Enterprise Linux Eus and 5 more 2026-06-17 8.2 High
A flaw was found in libgnutls. A remote attacker, by sending an extremely short premaster secret during an RSA key exchange to a server using an RSA key backed by a PKCS#11 token, could trigger a short heap overread. This memory corruption vulnerability could lead to information disclosure.
CVE-2026-3833 2 Gnu, Redhat 8 Gnutls, Enterprise Linux, Enterprise Linux Eus and 5 more 2026-06-17 6.5 Medium
A flaw was found in gnutls. This vulnerability occurs because gnutls performs case-sensitive comparisons of `nameConstraints` labels, specifically for `dNSName` (DNS) or `rfc822Name` (email) constraints within `excludedSubtrees` or `permittedSubtrees`. A remote attacker can exploit this by crafting a leaf certificate with casing differences in the Subject Alternative Name (SAN), leading to a policy bypass where a certificate that should be rejected is instead accepted. This could result in unauthorized access or information disclosure.
CVE-2026-42010 2 Gnu, Redhat 8 Gnutls, Enterprise Linux, Enterprise Linux Eus and 5 more 2026-06-17 7.1 High
A flaw was found in gnutls. Servers configured with RSA-PSK (Rivest–Shamir–Adleman – Pre-Shared Key) wrongfully matched usernames containing a NUL character with truncated usernames. A remote attacker could exploit this by sending a specially crafted username, leading to an authentication bypass. This vulnerability allows an attacker to gain unauthorized access by circumventing the authentication process.
CVE-2026-42009 2 Gnu, Redhat 18 Gnutls, Enterprise Linux, Enterprise Linux Eus and 15 more 2026-06-17 7.5 High
A flaw was found in gnutls. A remote attacker could exploit an issue in the Datagram Transport Layer Security (DTLS) packet reordering logic. The comparator function, responsible for ordering DTLS packets by sequence numbers, did not correctly handle packets with duplicate sequence numbers. This could lead to unstable packet ordering or undefined behavior, resulting in a denial of service.
CVE-2026-33846 2 Gnu, Redhat 8 Gnutls, Enterprise Linux, Enterprise Linux Eus and 5 more 2026-06-17 7.5 High
A heap buffer overflow vulnerability exists in the DTLS handshake fragment reassembly logic of GnuTLS. The issue arises in merge_handshake_packet() where incoming handshake fragments are matched and merged based solely on handshake type, without validating that the message_length field remains consistent across all fragments of the same logical message. An attacker can exploit this by sending crafted DTLS fragments with conflicting message_length values, causing the implementation to allocate a buffer based on a smaller initial fragment and subsequently write beyond its bounds using larger, inconsistent fragments. Because the merge operation does not enforce proper bounds checking against the allocated buffer size, this results in an out-of-bounds write on the heap. The vulnerability is remotely exploitable without authentication via the DTLS handshake path and can lead to application crashes or potential memory corruption.
CVE-2026-33845 2 Gnu, Redhat 8 Gnutls, Enterprise Linux, Enterprise Linux Eus and 5 more 2026-06-17 7.5 High
A flaw in GnuTLS DTLS handshake parsing allows malformed fragments with zero length and non-zero offset, leading to an integer underflow during reassembly and resulting in an out-of-bounds read. This issue is remotely exploitable and may cause information disclosure or denial of service.
CVE-2026-48829 1 Gnu 1 Gnu Sasl 2026-06-05 7.5 High
In GNU SASL before 2.2.3, DIGEST-MD5 has a NULL pointer dereference affecting both clients and servers, via a known token with no accompanying = character. This occurs in lib/digest-md5/getsubopt.c.
CVE-2026-33554 1 Gnu 1 Freeipmi 2026-06-03 7.5 High
ipmi-oem in FreeIPMI before 1.6.17 has exploitable buffer overflows on response messages. The Intelligent Platform Management Interface (IPMI) specification defines a set of interfaces for platform management. It is implemented by a large number of hardware manufacturers to support system management. It is most commonly used for sensor reading (e.g., CPU temperatures through the ipmi-sensors command within FreeIPMI) and remote power control (the ipmipower command). The ipmi-oem client command implements a set of a IPMI OEM commands for specific hardware vendors. If a user has supported hardware, they may wish to use the ipmi-oem command to send a request to a server to retrieve specific information. Three subcommands were found to have exploitable buffer overflows on response messages. They are: "ipmi-oem dell get-last-post-code - get the last POST code and string describing the error on some Dell servers," "ipmi-oem supermicro extra-firmware-info - get extra firmware info on Supermicro servers," and "ipmi-oem wistron read-proprietary-string - read a proprietary string on Wistron servers."
