Name of the Vulnerable Software and Affected Versions libmspack version 0.5alpha ClamAV version 0.99.2

Description The issue allows remote attackers to cause a denial of service, resulting in a stack-based buffer over-read and application crash, via a crafted CAB file. This is due to a problem in the cabd read string function in mspack/cabd.c.

Recommendations For libmspack version 0.5alpha, consider disabling the cabd read string function until a patch is available. For ClamAV version 0.99.2, restrict the processing of CAB files to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
