Untrusted search path vulnerability in the add_filename_to_string function in intl/gettext/loadmsgcat.c for Elinks 0.11.1 allows local users to cause Elinks to use an untrusted gettext message catalog (.po file) in a "../po" directory, which can be leveraged to conduct format string attacks.
CVSS Severity (version 2.0):
Impact Subscore: 6.4
Exploitability Subscore: 3.4
CVSS Version 2 Metrics:
Access Vector: Locally exploitable; Victim must voluntarily interact with attack mechanism
Access Complexity: Medium
Authentication: Not required to exploit
Impact Type: Allows unauthorized disclosure of information; Allows unauthorized modification; Allows disruption of service
An untrusted message catalog might lead to a format-string attack when an
attacker tricks user into launching links from a particular directory.
