Description

Updated libmspack/cabextract packages fix security vulnerabilities Hanno Böck discovered that libmspack incorrectly handled certain CHM files. An attacker could possibly use this issue to cause a denial of service (CVE-2018-14679, CVE-2018-14680). Jakub Wilk discovered that libmspack incorrectly handled certain KWAJ files. An attacker could possibly use this issue to execute arbitrary code (CVE-2018-14681). Dmitry Glavatskikh discovered that libmspack incorrectly certain CHM files. An attacker could possibly use this issue to execute arbitrary code (CVE-2018-14682). If a CAB file has a Quantum-compressed datablock with exactly 38912 compressed bytes, cabextract would write exactly one byte beyond its input buffer (CVE-2018-18584). libmspack didn't reject blank CHM filenames that are blank because they have embedded null bytes, not just because they are zero-length (CVE-2018-18585). chmextract didn't protect from absolute/relative pathnames in CHM files (CVE-2018-18586).
