CVE-2020-27618

The iconv function in the GNU C Library aka glibc or libc6 2.32 and earlier, when processing invalid multi-byte input sequences in IBM1364, IBM1371, IBM1388, IBM1390, and IBM1399 encodings, fails to advance the input state, which could lead to an infinite loop in applications, resulting in a deni...

CVE-2020-27618

Summary (CVE-2020-27618) The vulnerability affects the GNU C Library (glibc) iconv input handling. When processing invalid multi-byte input sequences in specific IBM encodings, iconv may fail to advance the input state, potentially causing an infinite loop and a denial of service. This behavior i...

CVE-2021-27645

The nameserver caching daemon nscd in the GNU C Library aka glibc or libc6 2.29 through 2.33, when processing a request for netgroup lookup, may crash due to a double-free, potentially resulting in degraded service or Denial of Service on the local system. This is related to netgroupcache.c...

Double free

The nameserver caching daemon nscd in the GNU C Library aka glibc or libc6 2.29 through 2.33, when processing a request for netgroup lookup, may crash due to a double-free, potentially resulting in degraded service or Denial of Service on the local system. This is related to netgroupcache.c...

CVE-2021-27645

CVE-2021-27645 affects the GNU C Library (glibc) nscd: a double-free in netgroupcache.c may crash the nameserver caching daemon and cause local Denial of Service. Public reports reference glibc versions 2.29–2.33 as affected, with remediation via security updates. Debian’s DLA-3152-1 (glibc 2.28-...

Important: glibc

Issue Overview: 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...

CVE-2021-3326

CVE-2021-3326 affects the GNU C Library (glibc) iconv implementation. When processing invalid input sequences for ISO-2022-JP-3, glibc 2.32 and earlier can trigger an assertion failure and abort, potentially leading to a denial of service. Public vendor advisories and post-release notes confirm t...
