Description

This security bulletin contains information about 1 vulnerability.


1) Infinite loop (CVE-ID: CVE-2018-9251)

CWE-ID: CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')

CVSSv4: 5.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to cause DoS condition on the target system.

The vulnerability exists in the xz_decomp() function of the GNOME libxml2 library, as defined in the xzlib.c source code due to an infinite loop condition in the Lempel-Ziv-Markov (LZMA) decompression feature during the processing of XML files. A remote unauthenticated attacker can trick the victim into opening a specially crafted XML file that submits malicious input, trigger an LZMA_MEMLIMIT_ERROR condition and cause the application to crash.
