Debian DSA-3946-1 : libmspack - security update

high Nessus Plugin ID 102598
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The remote Debian host is missing a security-related update.


It was discovered that libsmpack, a library used to handle Microsoft compression formats, did not properly validate its input. A remote attacker could craft malicious CAB or CHM files and use this flaw to cause a denial of service via application crash, or potentially execute arbitrary code.


Upgrade the libmspack packages.

For the oldstable distribution (jessie), these problems have been fixed in version 0.5-1+deb8u1.

For the stable distribution (stretch), these problems have been fixed in version 0.5-1+deb9u1.
