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 2025-04-12 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 2025-04-12 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.

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 2025-04-12 7.5 HIGH 9.8 CRITICAL
Multiple stack-based buffer overflows in the GNU C Library (aka glibc or libc6) before 2.23 allow context-dependent attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a long argument to the (1) nan, (2) nanf, or (3) nanl function.
CVE-2013-7424 1 Gnu 1 Glibc 2025-04-12 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 2025-04-12 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 2025-04-12 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 2025-04-12 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-2013-0242 1 Gnu 1 Glibc 2025-04-11 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.
CVE-2011-1089 1 Gnu 1 Glibc 2025-04-11 3.3 LOW N/A
The addmntent function in the GNU C Library (aka glibc or libc6) 2.13 and earlier does not report an error status for failed attempts to write to the /etc/mtab file, which makes it easier for local users to trigger corruption of this file, as demonstrated by writes from a process with a small RLIMIT_FSIZE value, a different vulnerability than CVE-2010-0296.
CVE-2010-4052 1 Gnu 1 Glibc 2025-04-11 5.0 MEDIUM N/A
Stack consumption vulnerability in 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 (resource exhaustion) via a regular expression containing adjacent repetition operators, as demonstrated by a {10,}{10,}{10,}{10,} sequence in the proftpd.gnu.c exploit for ProFTPD.
CVE-2012-3405 3 Canonical, Gnu, Redhat 4 Ubuntu Linux, Glibc, Enterprise Linux and 1 more 2025-04-11 5.0 MEDIUM N/A
The vfprintf function in stdio-common/vfprintf.c in libc in GNU C Library (aka glibc) 2.14 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 (segmentation fault and crash) via a format string with a large number of format specifiers that triggers "desynchronization within the buffer size handling," a different vulnerability than CVE-2012-3404.
CVE-2013-4237 1 Gnu 1 Glibc 2025-04-11 6.8 MEDIUM N/A
sysdeps/posix/readdir_r.c in the GNU C Library (aka glibc or libc6) 2.18 and earlier allows context-dependent attackers to cause a denial of service (out-of-bounds write and crash) or possibly execute arbitrary code via a crafted (1) NTFS or (2) CIFS image.
CVE-2012-4424 1 Gnu 1 Glibc 2025-04-11 5.1 MEDIUM N/A
Stack-based buffer overflow in string/strcoll_l.c in the GNU C Library (aka glibc or libc6) 2.17 and earlier allows context-dependent attackers to cause a denial of service (crash) or possibly execute arbitrary code via a long string that triggers a malloc failure and use of the alloca function.
CVE-2013-4332 2 Gnu, Redhat 2 Glibc, Enterprise Linux 2025-04-11 4.3 MEDIUM N/A
Multiple integer overflows in malloc/malloc.c in the GNU C Library (aka glibc or libc6) 2.18 and earlier allow context-dependent attackers to cause a denial of service (heap corruption) via a large value to the (1) pvalloc, (2) valloc, (3) posix_memalign, (4) memalign, or (5) aligned_alloc functions.
CVE-2012-4412 1 Gnu 1 Glibc 2025-04-11 7.5 HIGH N/A
Integer overflow in string/strcoll_l.c in the GNU C Library (aka glibc or libc6) 2.17 and earlier allows context-dependent attackers to cause a denial of service (crash) or possibly execute arbitrary code via a long string, which triggers a heap-based buffer overflow.
CVE-2012-3406 3 Canonical, Gnu, Redhat 4 Ubuntu Linux, Glibc, Enterprise Linux and 1 more 2025-04-11 6.8 MEDIUM N/A
The vfprintf function in stdio-common/vfprintf.c in GNU C Library (aka glibc) 2.5, 2.12, and probably other versions does not "properly restrict the use of" the alloca function when allocating the SPECS array, which allows context-dependent attackers to bypass the FORTIFY_SOURCE format-string protection mechanism and cause a denial of service (crash) or possibly execute arbitrary code via a crafted format string using positional parameters and a large number of format specifiers, a different vulnerability than CVE-2012-3404 and CVE-2012-3405.
CVE-2013-2207 2 Fedoraproject, Gnu 2 Fedora, Glibc 2025-04-11 2.6 LOW N/A
