Base vector

AV:N/AC:M/Au:N/C:N/I:N/A:P

Name of the Vulnerable Software and Affected Versions libmspack versions prior to 0.5

Description The issue concerns the chmd init decomp function in chmd.c, which does not properly validate the reset interval. This allows remote attackers to cause a denial of service, resulting in a divide-by-zero error and application crash, via a crafted CHM file.

Recommendations For versions prior to 0.5, update to version 0.5 or later to resolve the issue. As a temporary workaround, consider restricting the use of crafted CHM files to minimize the risk of exploitation.
