GNU C Library could allow a remote attacker to execute arbitrary code on the system, caused by an out-of-bounds write in the ISO-2022-CN-EXT plugin. By sending specially crafted input, an attacker could exploit this vulnerability to overwrite critical data structures and execute arbitrary code on the system or cause the application to crash.
