|---|---|---|---|---|---|
| CVE-2017-16997 | 2 Gnu, Redhat | 4 Glibc, Enterprise Linux Desktop, Enterprise Linux Server and 1 more | 2025-04-20 | 9.3 HIGH | 7.8 HIGH |
| elf/dl-load.c in the GNU C Library (aka glibc or libc6) 2.19 through 2.26 mishandles RPATH and RUNPATH containing $ORIGIN for a privileged (setuid or AT_SECURE) program, which allows local users to gain privileges via a Trojan horse library in the current working directory, related to the fillin_rpath and decompose_rpath functions. This is associated with misinterpretion of an empty RPATH/RUNPATH token as the "./" directory. NOTE: this configuration of RPATH/RUNPATH for a privileged program is apparently very uncommon; most likely, no such program is shipped with any common Linux distribution. | |||||
| CVE-2017-17426 | 1 Gnu | 1 Glibc | 2025-04-20 | 6.8 MEDIUM | 8.1 HIGH |
| The malloc function in the GNU C Library (aka glibc or libc6) 2.26 could return a memory block that is too small if an attempt is made to allocate an object whose size is close to SIZE_MAX, potentially leading to a subsequent heap overflow. This occurs because the per-thread cache (aka tcache) feature enables a code path that lacks an integer overflow check. | |||||
| CVE-2017-8804 | 1 Gnu | 1 Glibc | 2025-04-20 | 7.8 HIGH | 7.5 HIGH |
| The xdr_bytes and xdr_string functions in the GNU C Library (aka glibc or libc6) 2.25 mishandle failures of buffer deserialization, which allows remote attackers to cause a denial of service (virtual memory allocation, or memory consumption if an overcommit setting is not used) via a crafted UDP packet to port 111, a related issue to CVE-2017-8779. NOTE: [Information provided from upstream and references | |||||
| CVE-2016-10228 | 1 Gnu | 1 Glibc | 2025-04-20 | 4.3 MEDIUM | 5.9 MEDIUM |
| The iconv program in the GNU C Library (aka glibc or libc6) 2.31 and earlier, when invoked with multiple suffixes in the destination encoding (TRANSLATE or IGNORE) along with the -c option, enters an infinite loop when processing invalid multi-byte input sequences, leading to a denial of service. | |||||
| CVE-2011-5320 | 1 Gnu | 1 Glibc | 2025-04-20 | 2.1 LOW | 6.2 MEDIUM |
| scanf and related functions in glibc before 2.15 allow local users to cause a denial of service (segmentation fault) via a large string of 0s. | |||||
| CVE-2017-12132 | 1 Gnu | 1 Glibc | 2025-04-20 | 4.3 MEDIUM | 5.9 MEDIUM |
| The DNS stub resolver in the GNU C Library (aka glibc or libc6) before version 2.26, when EDNS support is enabled, will solicit large UDP responses from name servers, potentially simplifying off-path DNS spoofing attacks due to IP fragmentation. | |||||
| CVE-2017-15670 | 1 Gnu | 1 Glibc | 2025-04-20 | 7.5 HIGH | 9.8 CRITICAL |
| The GNU C Library (aka glibc or libc6) before 2.27 contains an off-by-one error leading to a heap-based buffer overflow in the glob function in glob.c, related to the processing of home directories using the ~ operator followed by a long string. | |||||
| CVE-2017-12133 | 1 Gnu | 1 Glibc | 2025-04-20 | 4.3 MEDIUM | 5.9 MEDIUM |
| Use-after-free vulnerability in the clntudp_call function in sunrpc/clnt_udp.c in the GNU C Library (aka glibc or libc6) before 2.26 allows remote attackers to have unspecified impact via vectors related to error path. | |||||
| CVE-2017-15804 | 1 Gnu | 1 Glibc | 2025-04-20 | 7.5 HIGH | 9.8 CRITICAL |
| The glob function in glob.c in the GNU C Library (aka glibc or libc6) before 2.27 contains a buffer overflow during unescaping of user names with the ~ operator. | |||||
| CVE-2017-1000366 | 8 Debian, Gnu, Mcafee and 5 more | 20 Debian Linux, Glibc, Web Gateway and 17 more | 2025-04-20 | 7.2 HIGH | 7.8 HIGH |
| glibc contains a vulnerability that allows specially crafted LD_LIBRARY_PATH values to manipulate the heap/stack, causing them to alias, potentially resulting in arbitrary code execution. Please note that additional hardening changes have been made to glibc to prevent manipulation of stack and heap memory but these issues are not directly exploitable, as such they have not been given a CVE. This affects glibc 2.25 and earlier. | |||||
| CVE-2015-8982 | 1 Gnu | 1 Glibc | 2025-04-20 | 6.8 MEDIUM | 8.1 HIGH |
| Integer overflow in the strxfrm function in the GNU C Library (aka glibc or libc6) before 2.21 allows context-dependent attackers to cause a denial of service (crash) or possibly execute arbitrary code via a long string, which triggers a stack-based buffer overflow. | |||||
| CVE-2015-7547 | 10 Canonical, Debian, F5 and 7 more | 30 Ubuntu Linux, Debian Linux, Big-ip Access Policy Manager and 27 more | 2025-04-12 | 6.8 MEDIUM | 8.1 HIGH |
| Multiple stack-based buffer overflows in the (1) send_dg and (2) send_vc functions in the libresolv library in the GNU C Library (aka glibc or libc6) before 2.23 allow remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via a crafted DNS response that triggers a call to the getaddrinfo function with the AF_UNSPEC or AF_INET6 address family, related to performing "dual A/AAAA DNS queries" and the libnss_dns.so.2 NSS module. | |||||
| CVE-2014-8121 | 3 Canonical, Gnu, Suse | 4 Ubuntu Linux, Glibc, Suse Linux Enterprise Desktop and 1 more | 2025-04-12 | 5.0 MEDIUM | N/A |
| DB_LOOKUP in nss_files/files-XXX.c in the Name Service Switch (NSS) in GNU C Library (aka glibc or libc6) 2.21 and earlier does not properly check if a file is open, which allows remote attackers to cause a denial of service (infinite loop) by performing a look-up on a database while iterating over it, which triggers the file pointer to be reset. | |||||
| 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-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-2015-8778 | 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 |
| Integer overflow 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 the size argument to the __hcreate_r function, which triggers out-of-bounds heap-memory access. | |||||
| 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. | |||||

| 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-2016-3706 | 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-2015-8776 | 6 Canonical, Debian, Fedoraproject and 3 more | 10 Ubuntu Linux, Debian Linux, Fedora and 7 more | 2025-04-12 | 6.4 MEDIUM | 9.1 CRITICAL |
