Name of the Vulnerable Software and Affected Versions Sam2p version 0.49.4

Description The issue is related to the use of memory after it has been freed in the MiniPS::delete0 function of the Sam2p image conversion utility. This can be exploited by a remote attacker to cause a denial of service. A crafted input can lead to a segmentation fault, resulting in a denial of service or possibly other unspecified impacts.

Recommendations For Sam2p version 0.49.4, as a temporary workaround, consider disabling the MiniPS::delete0 function until a patch is available. Restrict access to the vulnerable minips.cpp module to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
