Description

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition in "archive_wstring_append_from_mbs" in "archive_string.c" because of an incorrect "mbrtowc" or "mbtowc" call. A remote attacker can create a specially crafted archive file, trick the victim into opening it, trigger out-of-bounds read error and read contents of memory on the system.

Mitigation
