Name of the Vulnerable Software and Affected Versions fig2dev version 3.2.7b

Description The issue is related to a stack-based buffer overflow in the genptk text component of fig2dev, which can be exploited by converting a xfig file into ptk format. This allows a remote attacker to cause a denial of service.

Recommendations For fig2dev version 3.2.7b, consider disabling the genptk text component in genptk.c as a temporary workaround to minimize the risk of exploitation. Restrict access to converting xfig files into ptk format until a patch is available.
