CVE-2026-1858 1 Gnu 1 Wget2 2026-04-30 4.8 Medium
wget2 accepts a server certificate with incorrect Key Usage (KU) or Extended Key Usage (EKU). If the attackers compromise a certificate (with the associated private key) issued for a different purpose, they may be able to reuse it for TLS server authentication.
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.

This CVE ID has been rejected or withdrawn by its CVE Numbering Authority.
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-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-2007-2500 1 Gnu 1 Flash Player 2026-04-23 N/A
server/parser/sprite_definition.cpp in GNU Gnash (aka GNU Flash Player) 0.7.2 allows remote attackers to execute arbitrary code via a large number of SHOWFRAME elements within a DEFINESPRITE element, which triggers memory corruption and enables the attacker to call free with an arbitrary address, probably resultant from a buffer overflow.
CVE-2007-6613 1 Gnu 1 Libcdio 2026-04-23 N/A
Stack-based buffer overflow in the print_iso9660_recurse function in iso-info (src/iso-info.c) in GNU Compact Disc Input and Control Library (libcdio) 0.79 and earlier allows context-dependent attackers to cause a denial of service (core dump) and possibly execute arbitrary code via a disk or image that contains a long joilet file name.
CVE-2008-4100 1 Gnu 1 Adns 2026-04-23 N/A
GNU adns 1.4 and earlier uses a fixed source port and sequential transaction IDs for DNS requests, which makes it easier for remote attackers to spoof DNS responses, a different vulnerability than CVE-2008-1447. NOTE: the vendor reports that this is intended behavior and is compatible with the product's intended role in a trusted environment.
CVE-2006-6235 6 Gnu, Gpg4win, Redhat and 3 more 9 Privacy Guard, Gpg4win, Enterprise Linux and 6 more 2026-04-23 N/A
A "stack overwrite" vulnerability in GnuPG (gpg) 1.x before 1.4.6, 2.x before 2.0.2, and 1.9.0 through 1.9.95 allows attackers to execute arbitrary code via crafted OpenPGP packets that cause GnuPG to dereference a function pointer from deallocated stack memory.
CVE-2006-7151 2 Gnu, Redhat 2 Libtool-ltdl, Fedora Core 2026-04-23 N/A
Untrusted search path vulnerability in the libtool-ltdl library (libltdl.so) 1.5.22-2.3 in Fedora Core 5 might allow local users to execute arbitrary code via a malicious library in the (1) hwcap, (2) 0, and (3) nosegneg subdirectories.
CVE-2009-3555 9 Apache, Canonical, Debian and 6 more 15 Http Server, Ubuntu Linux, Debian Linux and 12 more 2026-04-23 N/A
The TLS protocol, and the SSL protocol 3.0 and possibly earlier, as used in Microsoft Internet Information Services (IIS) 7.0, mod_ssl in the Apache HTTP Server 2.2.14 and earlier, OpenSSL before 0.9.8l, GnuTLS 2.8.5 and earlier, Mozilla Network Security Services (NSS) 3.12.4 and earlier, multiple Cisco products, and other products, does not properly associate renegotiation handshakes with an existing connection, which allows man-in-the-middle attackers to insert data into HTTPS sessions, and possibly other types of sessions protected by TLS or SSL, by sending an unauthenticated request that is processed retroactively by a server in a post-renegotiation context, related to a "plaintext injection" attack, aka the "Project Mogul" issue.
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-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-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-2009-1417 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-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-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-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-2008-3896 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.
