| 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-2026-40556 | 1 Gnu | 1 Nano | 2026-04-29 | N/A |
| This CVE ID has been rejected or withdrawn by its CVE Numbering Authority. | ||||
| CVE-2026-5450 | 2 Gnu, The Gnu C Library | 2 Glibc, Glibc | 2026-04-23 | 9.8 Critical |
| Calling the scanf family of functions with a %mc (malloc'd character match) in the GNU C Library version 2.7 to version 2.43 with a format width specifier with an explicit width greater than 1024 could result in a one byte heap buffer overflow. | ||||
| CVE-2008-1367 | 2 Gnu, Redhat | 2 Gcc, Enterprise Linux | 2026-04-23 | N/A |
| gcc 4.3.x does not generate a cld instruction while compiling functions used for string manipulation such as memcpy and memmove on x86 and i386, which can prevent the direction flag (DF) from being reset in violation of ABI conventions and cause data to be copied in the wrong direction during signal handling in the Linux kernel, which might allow context-dependent attackers to trigger memory corruption. NOTE: this issue was originally reported for CPU consumption in SBCL. | ||||
| CVE-2008-3896 | 1 Gnu | 1 Grub Legacy | 2026-04-23 | N/A |
| Grub Legacy 0.97 and earlier stores pre-boot authentication passwords in the BIOS Keyboard buffer and does not clear this buffer before and after use, which allows local users to obtain sensitive information by reading the physical memory locations associated with this buffer. | ||||
| CVE-2008-3863 | 2 Gnu, Redhat | 2 Enscript, Enterprise Linux | 2026-04-23 | N/A |
| Stack-based buffer overflow in the read_special_escape function in src/psgen.c in GNU Enscript 1.6.1 and 1.6.4 beta, when the -e (aka special escapes processing) option is enabled, allows user-assisted remote attackers to execute arbitrary code via a crafted ASCII file, related to the setfilename command. | ||||
| CVE-2008-1946 | 2 Gnu, Redhat | 2 Coreutils, Enterprise Linux | 2026-04-23 | N/A |
| The default configuration of su in /etc/pam.d/su in GNU coreutils 5.2.1 allows local users to gain the privileges of a (1) locked or (2) expired account by entering the account name on the command line, related to improper use of the pam_succeed_if.so module. | ||||
| CVE-2008-4475 | 1 Gnu | 1 Ibackup | 2026-04-23 | N/A |
| ibackup 2.27 allows local users to overwrite arbitrary files via a symlink attack on temporary files. | ||||
| CVE-2007-1269 | 1 Gnu | 1 Gnumail | 2026-04-23 | N/A |
| GNUMail 1.1.2 and earlier does not properly use the --status-fd argument when invoking GnuPG, which prevents GNUMail from visually distinguishing between signed and unsigned portions of OpenPGP messages with multiple components, which allows remote attackers to forge the contents of a message without detection. | ||||
| CVE-2008-1688 | 1 Gnu | 1 M4 | 2026-04-23 | N/A |
| Unspecified vulnerability in GNU m4 before 1.4.11 might allow context-dependent attackers to execute arbitrary code, related to improper handling of filenames specified with the -F option. NOTE: it is not clear when this issue crosses privilege boundaries. | ||||
| CVE-2006-4573 | 1 Gnu | 1 Screen | 2026-04-23 | N/A |
| Multiple unspecified vulnerabilities in the "utf8 combining characters handling" (utf8_handle_comb function in encoding.c) in screen before 4.0.3 allows user-assisted attackers to cause a denial of service (crash or hang) via certain UTF8 sequences. | ||||
| CVE-2008-2377 | 1 Gnu | 1 Gnutls | 2026-04-23 | N/A |
| Use-after-free vulnerability in the _gnutls_handshake_hash_buffers_clear function in lib/gnutls_handshake.c in libgnutls in GnuTLS 2.3.5 through 2.4.0 allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via TLS transmission of data that is improperly used when the peer calls gnutls_handshake within a normal session, leading to attempted access to a deallocated libgcrypt handle. | ||||
| CVE-2007-6130 | 1 Gnu | 1 Gnump3d | 2026-04-23 | N/A |
| gnump3d 2.9final does not apply password protection to its plugins, which might allow remote attackers to bypass intended access restrictions. | ||||
| CVE-2008-3916 | 2 Gnu, Redhat | 2 Ed, Enterprise Linux | 2026-04-23 | N/A |
| Heap-based buffer overflow in the strip_escapes function in signal.c in GNU ed before 1.0 allows context-dependent or user-assisted attackers to execute arbitrary code via a long filename. NOTE: since ed itself does not typically run with special privileges, this issue only crosses privilege boundaries when ed is invoked as a third-party component. | ||||
| CVE-2008-1685 | 1 Gnu | 1 Gcc | 2026-04-23 | N/A |
| gcc 4.2.0 through 4.3.0 in GNU Compiler Collection, when casts are not used, considers the sum of a pointer and an int to be greater than or equal to the pointer, which might lead to removal of length testing code that was intended as a protection mechanism against integer overflow and buffer overflow attacks, and provide no diagnostic message about this removal. NOTE: the vendor has determined that this compiler behavior is correct according to section 6.5.6 of the C99 standard (aka ISO/IEC 9899:1999) | ||||
| CVE-2008-1687 | 1 Gnu | 1 M4 | 2026-04-23 | N/A |
| The (1) maketemp and (2) mkstemp builtin functions in GNU m4 before 1.4.11 do not quote their output when a file is created, which might allow context-dependent attackers to trigger a macro expansion, leading to unspecified use of an incorrect filename. | ||||
| CVE-2008-1950 | 2 Gnu, Redhat | 2 Gnutls, Enterprise Linux | 2026-04-23 | N/A |
| Integer signedness error in the _gnutls_ciphertext2compressed function in lib/gnutls_cipher.c in libgnutls in GnuTLS before 2.2.4 allows remote attackers to cause a denial of service (buffer over-read and crash) via a certain integer value in the Random field in an encrypted Client Hello message within a TLS record with an invalid Record Length, which leads to an invalid cipher padding length, aka GNUTLS-SA-2008-1-3. | ||||
| CVE-2008-1948 | 2 Gnu, Redhat | 2 Gnutls, Enterprise Linux | 2026-04-23 | N/A |
| The _gnutls_server_name_recv_params function in lib/ext_server_name.c in libgnutls in gnutls-serv in GnuTLS before 2.2.4 does not properly calculate the number of Server Names in a TLS 1.0 Client Hello message during extension handling, which allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via a zero value for the length of Server Names, which leads to a buffer overflow in session resumption data in the pack_security_parameters function, aka GNUTLS-SA-2008-1-1. | ||||
