Description
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The vulnerability exists in the xz_head() function of the GNOME libxml2 library, as defined in the xzlib.c source code due to boundary error in the Lempel-Ziv-Markov (LZMA) decompression feature. A remote unauthenticated attacker can trick the victim into opening a specially crafted LZMA file that submits malicious input, trigger memory corruption and cause the application to crash.
