NVD Description

Note: Versions mentioned in the description apply only to the upstream glibc-langpack-si package and not the glibc-langpack-si package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

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 denial of service, a different vulnerability from CVE-2016-10228.
