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

Description The issue is related to a buffer overflow in the conv pattern index function of the gencgm.c component in the fig2dev utility. This occurs due to the lack of input validation, allowing a remote attacker to cause a denial of service. The conv pattern index function is vulnerable to a global buffer overflow.

Recommendations For fig2dev version 3.2.7b, consider disabling the conv pattern index function in gencgm.c as a temporary workaround to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
