Published: Translated: NVD NIST

Summary

In the pcfGetProperties function in bitmap/pcfread.c in libXfont through 1.5.2 and 2.x before 2.0.2, a missing boundary check could be exploited by local attackers authenticated to an Xserver for a buffer over-read, leading to information disclosure or a crash of the X server.

Risk Assessment

The lack of boundary checks may lead to the disclosure of sensitive information or destabilization of the X server, potentially impacting the availability of services within the organization.

Recommendation
