glibc vulnerability CVE-2021-3326

The iconv function in the GNU C Library (aka glibc or libc6) 2.32 and earlier, when processing invalid input sequences in the ISO-2022-JP-3 encoding, fails an assertion in the code path and aborts the program, potentially resulting in a denial of service. (CVE-2021-3326)

Impact

An attacker can exploit this vulnerability by crafting a sequence of characters to an application using the iconv function and cause the application to be terminated abnormally.
