ALSA-2021:1585

The glibc packages provide the standard C libraries (libc), POSIX thread libraries (libpthread), standard math libraries (libm), and the name service cache daemon (nscd) used by multiple programs on the system. Without these libraries, the Linux system cannot function correctly.

Security Fix(es):

• glibc: buffer over-read in iconv when processing invalid multi-byte input sequences in the EUC-KR encoding (CVE-2019-25013)

• glibc: regular-expression match via proceednextnode in posix/regexec.c leads to heap-based buffer over-read (CVE-2019-9169)

• glibc: assertion failure in ISO-2022-JP-3 gconv module related to combining characters (CVE-2021-3326)

• glibc: iconv program can hang when invoked with the -c option (CVE-2016-10228)

• glibc: iconv when processing invalid multi-byte input sequences fails to advance the input state, which could result in an infinite loop (CVE-2020-27618)
