CVE-2015-8779 6 Canonical, Debian, Fedoraproject and 3 more 10 Ubuntu Linux, Debian Linux, Fedora and 7 more 2025-04-12 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-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-2016-2856 3 Canonical, Debian, Gnu 3 Ubuntu Linux, Debian Linux, Glibc 2025-04-12 7.2 HIGH 8.4 HIGH
pt_chown in the glibc package before 2.19-18+deb8u4 on Debian jessie; the elibc package before 2.15-0ubuntu10.14 on Ubuntu 12.04 LTS and before 2.19-0ubuntu6.8 on Ubuntu 14.04 LTS; and the glibc package before 2.21-0ubuntu4.2 on Ubuntu 15.10 and before 2.23-0ubuntu1 on Ubuntu 16.04 LTS and 16.10 lacks a namespace check associated with file-descriptor passing, which allows local users to capture keystrokes and spoof data, and possibly gain privileges, via pts read and write operations, related to debian/sysdeps/linux.mk. NOTE: this is not considered a vulnerability in the upstream GNU C Library because the upstream documentation has a clear security recommendation against the --enable-pt_chown option.
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.
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-2014-7817 4 Canonical, Debian, Gnu and 1 more 4 Ubuntu Linux, Debian Linux, Glibc and 1 more 2025-04-12 4.6 MEDIUM N/A
The wordexp function in GNU C Library (aka glibc) 2.21 does not enforce the WRDE_NOCMD flag, which allows context-dependent attackers to execute arbitrary commands, as demonstrated by input containing "$((`...`))".
CVE-2016-6323 3 Fedoraproject, Gnu, Opensuse 3 Fedora, Glibc, Opensuse 2025-04-12 5.0 MEDIUM 7.5 HIGH
The makecontext function in the GNU C Library (aka glibc or libc6) before 2.25 creates execution contexts incompatible with the unwinder on ARM EABI (32-bit) platforms, which might allow context-dependent attackers to cause a denial of service (hang), as demonstrated by applications compiled using gccgo, related to backtrace generation.
CVE-2012-6656 3 Canonical, Debian, Gnu 3 Ubuntu Linux, Debian Linux, Glibc 2025-04-12 5.0 MEDIUM N/A
iconvdata/ibm930.c in GNU C Library (aka glibc) before 2.16 allows context-dependent attackers to cause a denial of service (out-of-bounds read) via a multibyte character value of "0xffff" to the iconv function when converting IBM930 encoded data to UTF-8.
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-2016-3706 2 Gnu, Opensuse 2 Glibc, Opensuse 2025-04-12 5.0 MEDIUM 7.5 HIGH
Stack-based buffer overflow in the getaddrinfo function in sysdeps/posix/getaddrinfo.c in the GNU C Library (aka glibc or libc6) allows remote attackers to cause a denial of service (crash) via vectors involving hostent conversion. NOTE: this vulnerability exists because of an incomplete fix for CVE-2013-4458.
CVE-2013-7423 4 Canonical, Gnu, Opensuse and 1 more 4 Ubuntu Linux, Glibc, Opensuse and 1 more 2025-04-12 5.0 MEDIUM N/A
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-2015-8777 1 Gnu 1 Glibc 2025-04-12 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-2011-1071 1 Gnu 2 Eglibc, Glibc 2025-04-11 5.1 MEDIUM N/A
The GNU C Library (aka glibc or libc6) before 2.12.2 and Embedded GLIBC (EGLIBC) allow context-dependent attackers to execute arbitrary code or cause a denial of service (memory consumption) via a long UTF8 string that is used in an fnmatch call, aka a "stack extension attack," a related issue to CVE-2010-2898, CVE-2010-1917, and CVE-2007-4782, as originally reported for use of this library by Google Chrome.
CVE-2009-4880 1 Gnu 1 Glibc 2025-04-11 5.0 MEDIUM N/A
Multiple integer overflows in the strfmon implementation in the GNU C Library (aka glibc or libc6) 2.10.1 and earlier allow context-dependent attackers to cause a denial of service (memory consumption or application crash) via a crafted format string, as demonstrated by a crafted first argument to the money_format function in PHP, a related issue to CVE-2008-1391.
CVE-2011-1658 1 Gnu 1 Glibc 2025-04-11 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 2025-04-11 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-2012-0864 1 Gnu 1 Glibc 2025-04-11 6.8 MEDIUM N/A
Integer overflow in the vfprintf function in stdio-common/vfprintf.c in glibc 2.14 and other versions allows context-dependent attackers to bypass the FORTIFY_SOURCE protection mechanism, conduct format string attacks, and write to arbitrary memory via a large number of arguments.
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-2013-4458 2 Gnu, Suse 3 Glibc, Linux Enterprise Debuginfo, Linux Enterprise Server 2025-04-11 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-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.
