Package        : xfig
Version        : 1:3.2.7a-3+deb10u1
CVE ID         : CVE-2021-40241
Debian Bug     : 992395

A security issue has been discovered in xfig, a diagramming tool for the
interactive generation of figures under X11.

CVE-2021-40241:
    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.
