Libmspack Project

First CVE: Feb 3, 2015Active for: 11 yearsTotal CVEs: 11
21.8
VTI Score
Low

Libmspack is a widely embedded compression-handling library that parses Microsoft cabinet and related archive formats across numerous downstream applications and tools. Despite its narrow product scope, the vendor's prominence in the software supply chain means that vulnerabilities in the library propagate broadly; the recurring weakness classes—improper bounds restrictions, out-of-bounds reads, and out-of-bounds writes—reflect the memory-safety challenges inherent to binary format parsing. Defenders should inventory products that bundle this library and prioritize patches accordingly, as remediation typically depends on downstream vendors rebuilding; live severity, exploitation, and exposure counts are shown alongside this summary.
