Synopsis ========
A vulnerability in Kpathsea allows remote attackers to execute arbitrary commands by manipulating the -tex option from mpost program.
Background ==========
Kpathsea is a library to do path searching. It is used by TeX Live and others TeX related software.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-libs/kpathsea < 6.2.2_p20160523 >= 6.2.2_p20160523
Description ===========
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.
Resolution ==========
All Kpathsea users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot -v ">=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.
