- Date Reported:
- 05 Mar 2023
- Affected Packages:
- Security database references:
- In the Debian bugtracking system: Bug 992395.
In Mitre's CVE dictionary: CVE-2021-40241.
- More information:
A security issue has been discovered in xfig, a diagramming tool for the interactive generation of figures under X11.
A potential buffer overflow exists in the file src/w_help.c at line 55. Specifically, the length of the string returned by getenv("LANG") may become very long and cause a buffer overflow while executing the sprintf() function. This vulnerability could potentially allow an attacker to execute arbitrary code or cause a denial-of-service condition.
For Debian 10 buster, this problem has been fixed in version 1:3.2.7a-3+deb10u1.
We recommend that you upgrade your xfig packages.
