| 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| This CVE ID has been rejected or withdrawn by its CVE Numbering Authority.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-2025-69720 | 2 Gnu, Invisible-island | 2 Ncurses, Ncurses | 2026-04-23 | 7.3 High |
| The infocmp command-line tool in ncurses before 6.5-20251213 has a stack-based buffer overflow in analyze_string in progs/infocmp.c. | ||||
| CVE-2007-2162 | 2 Gnu, Mozilla | 2 Iceweasel, Firefox | 2026-04-23 | N/A |
| (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-2008-5659 | 1 Gnu | 1 Classpath | 2026-04-23 | N/A |
| The gnu.java.security.util.PRNG class in GNU Classpath 0.97.2 and earlier uses a predictable seed based on the system time, which makes it easier for context-dependent attackers to conduct brute force attacks against cryptographic routines that use this class for randomness, as demonstrated against DSA private keys. | ||||
| CVE-2007-2808 | 2 Gnu, Yngve Svendsen | 2 Gnats, Gnatsweb | 2026-04-23 | N/A |
| Cross-site scripting (XSS) vulnerability in gnatsweb.pl in Gnatsweb 4.00 and Gnats 4.1.99 allows remote attackers to inject arbitrary web script or HTML via the database parameter. | ||||
| 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-2007-1263 | 3 Gnu, Gnupg, Redhat | 3 Gpgme, Gnupg, Enterprise Linux | 2026-04-23 | N/A |
| GnuPG 1.4.6 and earlier and GPGME before 1.1.4, when run from the command line, does not visually distinguish signed and unsigned portions of OpenPGP messages with multiple components, which might allow remote attackers to forge the contents of a message without detection. | ||||
| CVE-2006-4181 | 1 Gnu | 1 Radius | 2026-04-23 | N/A |
| Format string vulnerability in the sqllog function in the SQL accounting code for radiusd in GNU Radius 1.2 and 1.3 allows remote attackers to execute arbitrary code via unknown vectors. | ||||
| CVE-2009-3736 | 2 Gnu, Redhat | 2 Libtool, Enterprise Linux | 2026-04-23 | N/A |
| 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-2009-1390 | 3 Gnu, Mutt, Openssl | 3 Gnutls, Mutt, Openssl | 2026-04-23 | N/A |
| Mutt 1.5.19, when linked against (1) OpenSSL (mutt_ssl.c) or (2) GnuTLS (mutt_ssl_gnutls.c), allows connections when only one TLS certificate in the chain is accepted instead of verifying the entire chain, which allows remote attackers to spoof trusted servers via a man-in-the-middle attack. | ||||
| CVE-2009-1417 | 1 Gnu | 1 Gnutls | 2026-04-23 | N/A |
| gnutls-cli in GnuTLS before 2.6.6 does not verify the activation and expiration times of X.509 certificates, which allows remote attackers to successfully present a certificate that is (1) not yet valid or (2) no longer valid, related to lack of time checks in the _gnutls_x509_verify_certificate function in lib/x509/verify.c in libgnutls_x509, as used by (a) Exim, (b) OpenLDAP, and (c) libsoup. | ||||
| 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-2010-0002 | 1 Gnu | 1 Bash | 2026-04-23 | N/A |
| The /etc/profile.d/60alias.sh script in the Mandriva bash package for Bash 2.05b, 3.0, 3.2, 3.2.48, and 4.0 enables the --show-control-chars option in LS_OPTIONS, which allows local users to send escape sequences to terminal emulators, or hide the existence of a file, via a crafted filename. | ||||
| 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-2009-4128 | 1 Gnu | 1 Grub 2 | 2026-04-23 | N/A |
| GNU GRand Unified Bootloader (GRUB) 2 1.97 only compares the submitted portion of a password with the actual password, which makes it easier for physically proximate attackers to conduct brute force attacks and bypass authentication by submitting a password whose length is 1. | ||||
| CVE-2009-4135 | 3 Canonical, Fedoraproject, Gnu | 3 Ubuntu Linux, Fedora, Coreutils | 2026-04-23 | N/A |
| The distcheck rule in dist-check.mk in GNU coreutils 5.2.1 through 8.1 allows local users to gain privileges via a symlink attack on a file in a directory tree under /tmp. | ||||
