| CVE-2026-33846 | 2 Gnu, Redhat | 6 Gnutls, Enterprise Linux, Hardened Images and 3 more | 2026-05-04 | 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-2026-6238 | 3 Gnu, Redhat, The Gnu C Library | 3 Glibc, Hummingbird, Glibc | 2026-05-04 | 6.5 Medium |
| The deprecated functions ns_printrrf, ns_printrr and fp_nquery in the GNU C Library version 2.2 and newer fail to validate the RDATA content against the RDATA length in a DNS response when processing LOC, CERT, 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-2026-1584 | 2 Gnu, Redhat | 5 Gnutls, Enterprise Linux, Hardened Images and 2 more | 2026-05-03 | 7.5 High |
| A flaw was found in gnutls. A remote, unauthenticated attacker can exploit this vulnerability by sending a specially crafted ClientHello message with an invalid Pre-Shared Key (PSK) binder value during the TLS handshake. This can lead to a NULL pointer dereference, causing the server to crash and resulting in a remote Denial of Service (DoS) condition. | ||||
| CVE-2026-5928 | 2 Gnu, The Gnu C Library | 2 Glibc, Glibc | 2026-04-30 | 7.5 High |
| Calling the ungetwc function on a FILE stream with wide characters encoded in a character set that has overlaps between its single byte and multi-byte character encodings, in the GNU C Library version 2.43 or earlier, may result in an attempt to read bytes before an allocated buffer, potentially resulting in unintentional disclosure of neighboring data in the heap, or a program crash. A bug in the wide character pushback implementation (_IO_wdefault_pbackfail in libio/wgenops.c) causes ungetwc() to operate on the regular character buffer (fp->_IO_read_ptr) instead of the actual wide-stream read pointer (fp->_wide_data->_IO_read_ptr). The program crash may happen in cases where fp->_IO_read_ptr is not initialized and hence points to NULL. The buffer under-read requires a special situation where the input character encoding is such that there are overlaps between single byte representations and multibyte representations in that encoding, resulting in spurious matches. The spurious match case is not possible in the standard Unicode character sets. | ||||
| CVE-2026-0861 | 1 Gnu | 1 Glibc | 2026-04-29 | 8.4 High |
| Passing too large an alignment to the memalign suite of functions (memalign, posix_memalign, aligned_alloc) in the GNU C Library version 2.30 to 2.42 may result in an integer overflow, which could consequently result in a heap corruption. Note that the attacker must have control over both, the size as well as the alignment arguments of the memalign function to be able to exploit this. The size parameter must be close enough to PTRDIFF_MAX so as to overflow size_t along with the large alignment argument. This limits the malicious inputs for the alignment for memalign to the range [1<<62+ 1, 1<<63] and exactly 1<<63 for posix_memalign and aligned_alloc. Typically the alignment argument passed to such functions is a known constrained quantity (e.g. page size, block size, struct sizes) and is not attacker controlled, because of which this may not be easily exploitable in practice. An application bug could potentially result in the input alignment being too large, e.g. due to a different buffer overflow or integer overflow in the application or its dependent libraries, but that is again an uncommon usage pattern given typical sources of alignments. | ||||

| CVE-2009-2409 | 4 Gnu, Mozilla, Openssl and 1 more | 7 Gnutls, Network Security Services, Openssl and 4 more | 2026-04-23 | N/A |
| The Network Security Services (NSS) library before 3.12.3, as used in Firefox; GnuTLS before 2.6.4 and 2.7.4; OpenSSL 0.9.8 through 0.9.8k; and other products support MD2 with X.509 certificates, which might allow remote attackers to spoof certificates by using MD2 design flaws to generate a hash collision in less than brute-force time. NOTE: the scope of this issue is currently limited because the amount of computation required is still large. | ||||

| (1) Mozilla Firefox 2.0.0.3 and (2) GNU IceWeasel 2.0.0.3 allow remote attackers to cause a denial of service (browser crash or system hang) via JavaScript that matches a regular expression against a long string, as demonstrated using /(.)*/. | ||||
| CVE-2009-3490 | 2 Gnu, Redhat | 2 Wget, Enterprise Linux | 2026-04-23 | N/A |
| GNU Wget before 1.12 does not properly handle a '\0' character in a domain name in the Common Name field of an X.509 certificate, which allows man-in-the-middle remote attackers to spoof arbitrary SSL servers via a crafted certificate issued by a legitimate Certification Authority, a related issue to CVE-2009-2408. | ||||
| CVE-2007-2452 | 1 Gnu | 1 Findutils | 2026-04-23 | N/A |
| Heap-based buffer overflow in the visit_old_format function in locate/locate.c in locate in GNU findutils before 4.2.31 might allow context-dependent attackers to execute arbitrary code via a long pathname in a locate database that has the old format, a different vulnerability than CVE-2001-1036. | ||||
| CVE-2009-1416 | 1 Gnu | 1 Gnutls | 2026-04-23 | N/A |
| lib/gnutls_pk.c in libgnutls in GnuTLS 2.5.0 through 2.6.5 generates RSA keys stored in DSA structures, instead of the intended DSA keys, which might allow remote attackers to spoof signatures on certificates or have unspecified other impact by leveraging an invalid DSA key. | ||||

| ltdl.c in libltdl in GNU Libtool 1.5.x, and 2.2.6 before 2.2.6b, as used in Ham Radio Control Libraries, Q, and possibly other products, attempts to open a .la file in the current working directory, which allows local users to gain privileges via a Trojan horse file. | ||||
| CVE-2009-2730 | 2 Gnu, Redhat | 2 Gnutls, Enterprise Linux | 2026-04-23 | N/A |
| libgnutls in GnuTLS before 2.8.2 does not properly handle a '\0' character in a domain name in the subject's (1) Common Name (CN) or (2) Subject Alternative Name (SAN) field of an X.509 certificate, which allows man-in-the-middle attackers to spoof arbitrary SSL servers via a crafted certificate issued by a legitimate Certification Authority. | ||||
| CVE-2006-6097 | 2 Gnu, Redhat | 2 Tar, Enterprise Linux | 2026-04-23 | N/A |
| GNU tar 1.16 and 1.15.1, and possibly other versions, allows user-assisted attackers to overwrite arbitrary files via a tar file that contains a GNUTYPE_NAMES record with a symbolic link, which is not properly handled by the extract_archive function in extract.c and extract_mangle function in mangle.c, a variant of CVE-2002-1216. | ||||
