CVE-2017-6419

mspack/lzxd.c in libmspack 0.5alpha, as used in ClamAV 0.99.2, allows remote attackers to cause a denial of service (heap-based buffer overflow and application crash) or possibly have unspecified other impact via a crafted CHM file.

mspack/lzxd.c in libmspack 0.5alpha, as used in ClamAV 0.99.2, allows remote attackers to cause a denial of service (heap-based buffer overflow and application crash) or possibly have unspecified other impact via a crafted CHM file.

It was discovered that libmspack incorrectly handled certain malformed CHM files. A remote attacker could use this issue to cause libmspack to crash, resulting in a denial of service, or possibly execute arbitrary code (CVE-2017-6419).
