CVE-2018-18586 (opens in a new tab)How to fix?
Upgrade SLES:15.2 libmspack0 to version 0.6-3.14.1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream libmspack0 package and not the libmspack0 package as distributed by SLES.
See How to fix? for SLES:15.2 relevant fixed versions and status.
chmextract.c in the chmextract sample program, as distributed with libmspack before 0.8alpha, does not protect against absolute/relative pathnames in CHM files, leading to Directory Traversal. NOTE: the vendor disputes that this is a libmspack vulnerability, because chmextract.c was only intended as a source-code example, not a supported application
