MGASA-2018-0455 - Updated libmspack/cabextract packages fix security vulnerabilities

Publication date: 17 Nov 2018
URL: https://advisories.mageia.org/MGASA-2018-0455.html
Type: security
Affected Mageia releases: 6
CVE: CVE-2018-14679,
     CVE-2018-14680,
     CVE-2018-14681,
     CVE-2018-14682,
     CVE-2018-18584,
     CVE-2018-18585,
     CVE-2018-18586

Hanno B?ck 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).
