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

Description The issue is related to a segmentation fault in the read objects function in read.c, which can be caused by reading beyond the valid boundaries of a data buffer. This can allow a remote attacker to cause a denial of service.

Recommendations For fig2dev version 3.2.7b, consider disabling the read objects function in read.c as a temporary workaround until a patch is available. Restrict access to the read.c component to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this issue.
