CVE-2010-4051 1 Gnu 1 Glibc 2026-04-29 5.0 MEDIUM N/A
The regcomp implementation in the GNU C Library (aka glibc or libc6) through 2.11.3, and 2.12.x through 2.12.2, allows context-dependent attackers to cause a denial of service (application crash) via a regular expression containing adjacent bounded repetitions that bypass the intended RE_DUP_MAX limitation, as demonstrated by a {10,}{10,}{10,}{10,}{10,} sequence in the proftpd.gnu.c exploit for ProFTPD, related to a "RE_DUP_MAX overflow."
CVE-2013-4122 2 Cmu, Gnu 2 Cyrus-sasl, Glibc 2026-04-29 4.3 MEDIUM N/A
Cyrus SASL 2.1.23, 2.1.26, and earlier does not properly handle when a NULL value is returned upon an error by the crypt function as implemented in glibc 2.17 and later, which allows remote attackers to cause a denial of service (thread crash and consumption) via (1) an invalid salt or, when FIPS-140 is enabled, a (2) DES or (3) MD5 encrypted password, which triggers a NULL pointer dereference.
CVE-2013-1914 1 Gnu 1 Glibc 2026-04-29 5.0 MEDIUM N/A
Stack-based buffer overflow in the getaddrinfo function in sysdeps/posix/getaddrinfo.c in GNU C Library (aka glibc or libc6) 2.17 and earlier allows remote attackers to cause a denial of service (crash) via a (1) hostname or (2) IP address that triggers a large number of domain conversion results.
CVE-2010-3192 1 Gnu 1 Glibc 2026-04-29 5.0 MEDIUM N/A
Certain run-time memory protection mechanisms in the GNU C Library (aka glibc or libc6) print argv[0] and backtrace information, which might allow context-dependent attackers to obtain sensitive information from process memory by executing an incorrect program, as demonstrated by a setuid program that contains a stack-based buffer overflow error, related to the __fortify_fail function in debug/fortify_fail.c, and the __stack_chk_fail (aka stack protection) and __chk_fail (aka FORTIFY_SOURCE) implementations.
CVE-2011-1659 1 Gnu 1 Glibc 2026-04-29 5.0 MEDIUM N/A
Integer overflow in posix/fnmatch.c in the GNU C Library (aka glibc or libc6) 2.13 and earlier allows context-dependent attackers to cause a denial of service (application crash) via a long UTF8 string that is used in an fnmatch call with a crafted pattern argument, a different vulnerability than CVE-2011-1071.
CVE-2009-5029 1 Gnu 1 Glibc 2026-04-29 6.8 MEDIUM N/A
Integer overflow in the __tzfile_read function in glibc before 2.15 allows context-dependent attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted timezone (TZ) file, as demonstrated using vsftpd.
CVE-2009-5064 1 Gnu 1 Glibc 2026-04-29 6.9 MEDIUM N/A
ldd in the GNU C Library (aka glibc or libc6) 2.13 and earlier allows local users to gain privileges via a Trojan horse executable file linked with a modified loader that omits certain LD_TRACE_LOADED_OBJECTS checks. NOTE: the GNU C Library vendor states "This is just nonsense. There are a gazillion other ways to introduce code if people are downloading arbitrary binaries and install them in appropriate directories or set LD_LIBRARY_PATH etc.
CVE-2013-4458 2 Gnu, Suse 3 Glibc, Linux Enterprise Debuginfo, Linux Enterprise Server 2026-04-29 5.0 MEDIUM N/A
Stack-based buffer overflow in the getaddrinfo function in sysdeps/posix/getaddrinfo.c in GNU C Library (aka glibc or libc6) 2.18 and earlier allows remote attackers to cause a denial of service (crash) via a (1) hostname or (2) IP address that triggers a large number of AF_INET6 address results. NOTE: this vulnerability exists because of an incomplete fix for CVE-2013-1914.
CVE-2012-3404 3 Canonical, Gnu, Redhat 4 Ubuntu Linux, Glibc, Enterprise Linux and 1 more 2026-04-29 5.0 MEDIUM N/A
The vfprintf function in stdio-common/vfprintf.c in libc in GNU C Library (aka glibc) 2.12 and other versions does not properly calculate a buffer length, which allows context-dependent attackers to bypass the FORTIFY_SOURCE format-string protection mechanism and cause a denial of service (stack corruption and crash) via a format string that uses positional parameters and many format specifiers.
CVE-2010-3847 1 Gnu 1 Glibc 2026-04-29 6.9 MEDIUM N/A
elf/dl-load.c in ld.so in the GNU C Library (aka glibc or libc6) through 2.11.2, and 2.12.x through 2.12.1, does not properly handle a value of $ORIGIN for the LD_AUDIT environment variable, which allows local users to gain privileges via a crafted dynamic shared object (DSO) located in an arbitrary directory.
CVE-2010-0830 1 Gnu 1 Glibc 2026-04-29 5.1 MEDIUM N/A
Integer signedness error in the elf_get_dynamic_info function in elf/dynamic-link.h in ld.so in the GNU C Library (aka glibc or libc6) 2.0.1 through 2.11.1, when the --verify option is used, allows user-assisted remote attackers to execute arbitrary code via a crafted ELF program with a negative value for a certain d_tag structure member in the ELF header.
CVE-2011-1658 1 Gnu 1 Glibc 2026-04-29 3.7 LOW N/A
ld.so in the GNU C Library (aka glibc or libc6) 2.13 and earlier expands the $ORIGIN dynamic string token when RPATH is composed entirely of this token, which might allow local users to gain privileges by creating a hard link in an arbitrary directory to a (1) setuid or (2) setgid program with this RPATH value, and then executing the program with a crafted value for the LD_PRELOAD environment variable, a different vulnerability than CVE-2010-3847 and CVE-2011-0536. NOTE: it is not expected that any standard operating-system distribution would ship an applicable setuid or setgid program.
CVE-2012-3480 1 Gnu 1 Glibc 2026-04-29 4.6 MEDIUM N/A
Multiple integer overflows in the (1) strtod, (2) strtof, (3) strtold, (4) strtod_l, and other unspecified "related functions" in stdlib in GNU C Library (aka glibc or libc6) 2.16 allow local users to cause a denial of service (application crash) and possibly execute arbitrary code via a long string, which triggers a stack-based buffer overflow.
CVE-2011-0536 2 Gnu, Redhat 2 Glibc, Enterprise Linux 2026-04-29 6.9 MEDIUM N/A
Multiple untrusted search path vulnerabilities in elf/dl-object.c in certain modified versions of the GNU C Library (aka glibc or libc6), including glibc-2.5-49.el5_5.6 and glibc-2.12-1.7.el6_0.3 in Red Hat Enterprise Linux, allow local users to gain privileges via a crafted dynamic shared object (DSO) in a subdirectory of the current working directory during execution of a (1) setuid or (2) setgid program that has $ORIGIN in (a) RPATH or (b) RUNPATH within the program itself or a referenced library. NOTE: this issue exists because of an incorrect fix for CVE-2010-3847.
CVE-2026-5928 1 Gnu 1 Glibc 2026-04-23 N/A 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 1 Gnu 1 Glibc 2026-04-23 N/A 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 7.5 HIGH 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 1 Gnu 1 Glibc 2026-04-20 N/A 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-2004-0968 2 Gnu, Redhat 3 Glibc, Enterprise Linux, Enterprise Linux Desktop 2026-04-16 2.1 LOW 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 7.5 HIGH N/A
The resolver in glibc 2.1.3 uses predictable IDs, which allows a local attacker to spoof DNS query results.
