NVD Description

Note: Versions mentioned in the description apply only to the upstream glibc package and not the glibc package as distributed by Ubuntu.

The iconv function in the GNU C Library (aka glibc or libc6) 2.30 to 2.32, when converting UCS4 text containing an irreversible character, fails an assertion in the code path and aborts the program, potentially resulting in a denial of service.
