GLSA-201709-07 : Kpathsea: User-assisted execution of arbitrary code

critical Nessus Plugin ID 103275

Language:

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-201709-07 (Kpathsea: User-assisted execution of arbitrary code)

 It was discovered that the mpost program from the shell_escape_commands list is capable of executing arbitrary external programs during the conversion of .tex files. The responsible function is runpopen() (texmfmp.c).
 Impact :

 A remote attacker, by enticing a user to open a specially crafted .tex file, could possibly execute arbitrary code with the privileges of the process.
 Workaround :

 There is no known workaround at this time.

Solution

All Kpathsea users should upgrade to the latest version:
 # emerge --sync # emerge --ask --oneshot --verbose '>=dev-libs/kpathsea-6.2.2_p20160523' Packages which depend on this library may need to be recompiled. Tools such as revdep-rebuild may assist in identifying some of these packages.
