Debian 10 Buster DLA-3353-1 Moderate: xfig Buffer Overflow Risk

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.
