| CVE-2026-5928 | 2 Gnu, The Gnu C Library | 2 Glibc, Glibc | 2026-04-23 | 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-2026-5450 | 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-2010-0015 | 1 Gnu | 1 Glibc | 2026-04-23 | N/A |
| nis/nss_nis/nis-pwd.c in the GNU C Library (aka glibc or libc6) 2.7 and Embedded GLIBC (EGLIBC) 2.10.2 adds information from the passwd.adjunct.byname map to entries in the passwd map, which allows remote attackers to obtain the encrypted passwords of NIS accounts by calling the getpwnam function. | ||||
| CVE-2026-4046 | 2 Gnu, The Gnu C Library | 2 Glibc, Glibc | 2026-04-20 | 7.5 High |
| The iconv() function in the GNU C Library versions 2.43 and earlier may crash due to an assertion failure when converting inputs from the IBM1390 or IBM1399 character sets, which may be used to remotely crash an application. This vulnerability can be trivially mitigated by removing the IBM1390 and IBM1399 character sets from systems that do not need them. | ||||
| CVE-2026-0915 | 1 Gnu | 1 Glibc | 2026-04-18 | 7.5 High |
| Calling getnetbyaddr or getnetbyaddr_r with a configured nsswitch.conf that specifies the library's DNS backend for networks and queries for a zero-valued network in the GNU C Library version 2.0 to version 2.42 can leak stack contents to the configured DNS resolver. | ||||
| CVE-2026-0861 | 1 Gnu | 1 Glibc | 2026-04-18 | 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-2004-1453 | 2 Gnu, Redhat | 2 Glibc, Enterprise Linux | 2026-04-16 | N/A |
| GNU glibc 2.3.4 before 2.3.4.20040619, 2.3.3 before 2.3.3.20040420, and 2.3.2 before 2.3.2-r10 does not restrict the use of LD_DEBUG for a setuid program, which allows local users to gain sensitive information, such as the list of symbols used by the program. | ||||
| CVE-2003-0028 | 11 Cray, Freebsd, Gnu and 8 more | 15 Unicos, Freebsd, Glibc and 12 more | 2026-04-16 | N/A |
| Integer overflow in the xdrmem_getbytes() function, and possibly other functions, of XDR (external data representation) libraries derived from SunRPC, including libnsl, libc, glibc, and dietlibc, allows remote attackers to execute arbitrary code via certain integer values in length fields, a different vulnerability than CVE-2002-0391. | ||||
| CVE-2004-1382 | 2 Gnu, Redhat | 2 Glibc, Enterprise Linux | 2026-04-16 | N/A |
| The glibcbug script in glibc 2.3.4 and earlier allows local users to overwrite arbitrary files via a symlink attack on temporary files, a different vulnerability than CVE-2004-0968. | ||||
| CVE-2003-0859 | 5 Gnu, Intel, Quagga and 2 more | 8 Glibc, Zebra, Ia64 and 5 more | 2026-04-16 | N/A |
| The getifaddrs function in GNU libc (glibc) 2.2.4 and earlier allows local users to cause a denial of service by sending spoofed messages as other users to the kernel netlink interface. | ||||
| CVE-2002-0684 | 3 Gnu, Isc, Redhat | 4 Glibc, Bind, Enterprise Linux and 1 more | 2026-04-16 | N/A |
| Buffer overflow in DNS resolver functions that perform lookup of network names and addresses, as used in BIND 4.9.8 and ported to glibc 2.2.5 and earlier, allows remote malicious DNS servers to execute arbitrary code through a subroutine used by functions such as getnetbyname and getnetbyaddr. | ||||
| CVE-2004-0968 | 2 Gnu, Redhat | 3 Glibc, Enterprise Linux, Enterprise Linux Desktop | 2026-04-16 | N/A |
| The catchsegv script in glibc 2.3.2 and earlier allows local users to overwrite files via a symlink attack on temporary files. | ||||
| CVE-2000-0335 | 2 Gnu, Isc | 2 Glibc, Bind | 2026-04-16 | N/A |
| The resolver in glibc 2.1.3 uses predictable IDs, which allows a local attacker to spoof DNS query results. | ||||
| CVE-2002-1265 | 3 Apple, Gnu, Sgi | 4 Mac Os X, Mac Os X Server, Glibc and 1 more | 2026-04-16 | N/A |
| The Sun RPC functionality in multiple libc implementations does not provide a time-out mechanism when reading data from TCP connections, which allows remote attackers to cause a denial of service (hang). | ||||
| CVE-2000-0959 | 1 Gnu | 1 Glibc | 2026-04-16 | N/A |
| glibc2 does not properly clear the LD_DEBUG_OUTPUT and LD_DEBUG environmental variables when a program is spawned from a setuid program, which could allow local users to overwrite files via a symlink attack. | ||||
| CVE-2000-0824 | 1 Gnu | 1 Glibc | 2026-04-16 | N/A |
| The unsetenv function in glibc 2.1.1 does not properly unset an environmental variable if the variable is provided twice to a program, which could allow local users to execute arbitrary commands in setuid programs by specifying their own duplicate environmental variables such as LD_PRELOAD or LD_LIBRARY_PATH. | ||||
| CVE-2002-1146 | 2 Gnu, Redhat | 3 Glibc, Enterprise Linux, Linux | 2026-04-16 | N/A |
| The BIND 4 and BIND 8.2.x stub resolver libraries, and other libraries such as glibc 2.2.5 and earlier, libc, and libresolv, use the maximum buffer size instead of the actual size when processing a DNS response, which causes the stub resolvers to read past the actual boundary ("read buffer overflow"), allowing remote attackers to cause a denial of service (crash). | ||||
| CVE-2025-8058 | 1 Gnu | 1 Glibc | 2026-04-15 | 4.2 Medium |
| The regcomp function in the GNU C library version from 2.4 to 2.41 is subject to a double free if some previous allocation fails. It can be accomplished either by a malloc failure or by using an interposed malloc that injects random malloc failures. The double free can allow buffer manipulation depending of how the regex is constructed. This issue affects all architectures and ABIs supported by the GNU C library. | ||||
| CVE-2026-3904 | 2 Gnu, The Gnu C Library | 2 Glibc, Glibc | 2026-04-10 | 6.2 Medium |
| Calling NSS-backed functions that support caching via nscd may call the nscd client side code and in the GNU C Library version 2.36 under high load on x86_64 systems, the client may call memcmp on inputs that are concurrently modified by other processes or threads and crash. The nscd client in the GNU C Library uses the memcmp function with inputs that may be concurrently modified by another thread, potentially resulting in spurious cache misses, which in itself is not a security issue. However in the GNU C Library version 2.36 an optimized implementation of memcmp was introduced for x86_64 which could crash when invoked with such undefined behaviour, turning this into a potential crash of the nscd client and the application that uses it. This implementation was backported to the 2.35 branch, making the nscd client in that branch vulnerable as well. Subsequently, the fix for this issue was backported to all vulnerable branches in the GNU C Library repository. It is advised that distributions that may have cherry-picked the memcpy SSE2 optimization in their copy of the GNU C Library, also apply the fix to avoid the potential crash in the nscd client. | ||||
| CVE-2026-4437 | 2 Gnu, The Gnu C Library | 2 Glibc, Glibc | 2026-04-08 | 7.5 High |
| Calling gethostbyaddr or gethostbyaddr_r with a configured nsswitch.conf that specifies the library's DNS backend in the GNU C Library version 2.34 to version 2.43 could, with a crafted response from the configured DNS server, result in a violation of the DNS specification that causes the application to treat a non-answer section of the DNS response as a valid answer. | ||||
