NVD Description

Note: Versions mentioned in the description apply only to the upstream liblouis-python package and not the liblouis-python package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

A vulnerability was found in liblouis, versions 2.5.x before 2.5.4. A stack-based buffer overflow was found in findTable() in liblouis. An attacker could create a malicious file that would cause applications that use liblouis (such as Orca) to crash, or potentially execute arbitrary code when opened.
