The send_dg function in resolv/res_send.c in GNU C Library (aka glibc or libc6) before 2.20 does not properly reuse file descriptors, which allows remote attackers to send DNS queries to unintended locations via a large number of requests that trigger a call to the getaddrinfo function.
CVE-2011-2702 1 Gnu 2 Eglibc, Glibc 2026-05-06 6.8 MEDIUM N/A
Integer signedness error in Glibc before 2.13 and eglibc before 2.13, when using Supplemental Streaming SIMD Extensions 3 (SSSE3) optimization, allows context-dependent attackers to execute arbitrary code via a negative length parameter to (1) memcpy-ssse3-rep.S, (2) memcpy-ssse3.S, or (3) memset-sse2.S in sysdeps/i386/i686/multiarch/, which triggers an out-of-bounds read, as demonstrated using the memcpy function.
CVE-2014-0475 1 Gnu 1 Glibc 2026-05-06 6.8 MEDIUM N/A
Multiple directory traversal vulnerabilities in GNU C Library (aka glibc or libc6) before 2.20 allow context-dependent attackers to bypass ForceCommand restrictions and possibly have other unspecified impact via a .. (dot dot) in a (1) LC_*, (2) LANG, or other locale environment variable.
CVE-2014-4043 2 Gnu, Opensuse 2 Glibc, Opensuse 2026-05-06 7.5 HIGH N/A
The posix_spawn_file_actions_addopen function in glibc before 2.20 does not copy its path argument in accordance with the POSIX specification, which allows context-dependent attackers to trigger use-after-free vulnerabilities.
CVE-2016-1234 3 Fedoraproject, Gnu, Opensuse 4 Fedora, Glibc, Leap and 1 more 2026-05-06 5.0 MEDIUM 7.5 HIGH

CVE-2014-5119 2 Debian, Gnu 2 Debian Linux, Glibc 2026-05-06 7.5 HIGH N/A
Off-by-one error in the __gconv_translit_find function in gconv_trans.c in GNU C Library (aka glibc) allows context-dependent attackers to cause a denial of service (crash) or execute arbitrary code via vectors related to the CHARSET environment variable and gconv transliteration modules.
CVE-2015-0235 7 Apple, Debian, Gnu and 4 more 18 Mac Os X, Debian Linux, Glibc and 15 more 2026-05-06 10.0 HIGH N/A
Heap-based buffer overflow in the __nss_hostname_digits_dots function in glibc 2.2, and other 2.x versions before 2.18, allows context-dependent attackers to execute arbitrary code via vectors related to the (1) gethostbyname or (2) gethostbyname2 function, aka "GHOST."
CVE-2015-8777 1 Gnu 1 Glibc 2026-05-06 2.1 LOW 5.5 MEDIUM
The process_envvars function in elf/rtld.c in the GNU C Library (aka glibc or libc6) before 2.23 allows local users to bypass a pointer-guarding protection mechanism via a zero value of the LD_POINTER_GUARD environment variable.
CVE-2015-1473 2 Canonical, Gnu 2 Ubuntu Linux, Glibc 2026-05-06 6.4 MEDIUM N/A
The ADDW macro in stdio-common/vfscanf.c in the GNU C Library (aka glibc or libc6) before 2.21 does not properly consider data-type size during a risk-management decision for use of the alloca function, which might allow context-dependent attackers to cause a denial of service (segmentation violation) or overwrite memory locations beyond the stack boundary via a long line containing wide characters that are improperly handled in a wscanf call.
CVE-2015-1781 4 Canonical, Debian, Gnu and 1 more 6 Ubuntu Linux, Debian Linux, Glibc and 3 more 2026-05-06 6.8 MEDIUM N/A
Buffer overflow in the gethostbyname_r and other unspecified NSS functions in the GNU C Library (aka glibc or libc6) before 2.22 allows context-dependent attackers to cause a denial of service (crash) or execute arbitrary code via a crafted DNS response, which triggers a call with a misaligned buffer.
CVE-2014-9402 3 Canonical, Gnu, Opensuse 3 Ubuntu Linux, Glibc, Opensuse 2026-05-06 7.8 HIGH N/A
The nss_dns implementation of getnetbyname in GNU C Library (aka glibc) before 2.21, when the DNS backend in the Name Service Switch configuration is enabled, allows remote attackers to cause a denial of service (infinite loop) by sending a positive answer while a network name is being process.
CVE-2015-8779 6 Canonical, Debian, Fedoraproject and 3 more 10 Ubuntu Linux, Debian Linux, Fedora and 7 more 2026-05-06 7.5 HIGH 9.8 CRITICAL
Stack-based buffer overflow in the catopen function in the GNU C Library (aka glibc or libc6) before 2.23 allows context-dependent attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a long catalog name.
CVE-2014-9761 5 Canonical, Fedoraproject, Gnu and 2 more 9 Ubuntu Linux, Fedora, Glibc and 6 more 2026-05-06 7.5 HIGH 9.8 CRITICAL

CVE-2013-7424 1 Gnu 1 Glibc 2026-05-06 5.1 MEDIUM N/A
The getaddrinfo function in glibc before 2.15, when compiled with libidn and the AI_IDN flag is used, allows context-dependent attackers to cause a denial of service (invalid free) and possibly execute arbitrary code via unspecified vectors, as demonstrated by an internationalized domain name to ping6.
CVE-2016-4429 3 Canonical, Gnu, Opensuse 4 Ubuntu Linux, Glibc, Leap and 1 more 2026-05-06 4.3 MEDIUM 5.9 MEDIUM
Stack-based buffer overflow in the clntudp_call function in sunrpc/clnt_udp.c in the GNU C Library (aka glibc or libc6) allows remote servers to cause a denial of service (crash) or possibly unspecified other impact via a flood of crafted ICMP and UDP packets.
CVE-2015-1472 2 Canonical, Gnu 2 Ubuntu Linux, Glibc 2026-05-06 7.5 HIGH N/A
The ADDW macro in stdio-common/vfscanf.c in the GNU C Library (aka glibc or libc6) before 2.21 does not properly consider data-type size during memory allocation, which allows context-dependent attackers to cause a denial of service (buffer overflow) or possibly have unspecified other impact via a long line containing wide characters that are improperly handled in a wscanf call.
CVE-2016-3075 4 Canonical, Fedoraproject, Gnu and 1 more 4 Ubuntu Linux, Fedora, Glibc and 1 more 2026-05-06 5.0 MEDIUM 7.5 HIGH
Stack-based buffer overflow in the nss_dns implementation of the getnetbyname function in GNU C Library (aka glibc) before 2.24 allows context-dependent attackers to cause a denial of service (stack consumption and application crash) via a long name.
CVE-2026-5435 1 Gnu 1 Glibc 2026-05-05 N/A 7.3 HIGH
The deprecated functions ns_printrrf, ns_printrr and fp_nquery in the GNU C Library version 2.2 and newer fail to enforce the caller-supplied buffer length, and can result in an out-of-bounds write when printing TSIG records.
CVE-2026-6238 1 Gnu 1 Glibc 2026-05-04 N/A 6.5 MEDIUM
The deprecated functions ns_printrrf, ns_printrr and fp_nquery in the GNU C Library version 2.2 and newer fail to validate the RDATA content against the RDATA length in a DNS response when processing LOC, CERT, TKEY or TSIG records, which may allow an attacker to craft a DNS response, causing a target application to crash or read uninitialized memory. These functions are for application debugging only and hence not in the path of code executed by the DNS resolver. Further, they have been deprecated since version 2.34 and should not be used by any new applications. Applications should consider porting away from these interfaces since they may be removed in future versions.
CVE-2013-0242 1 Gnu 1 Glibc 2026-04-29 5.0 MEDIUM N/A
Buffer overflow in the extend_buffers function in the regular expression matcher (posix/regexec.c) in glibc, possibly 2.17 and earlier, allows context-dependent attackers to cause a denial of service (memory corruption and crash) via crafted multibyte characters.
