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. References ========== [ 1 ] CVE-2016-10243 https://nvd.nist.gov/nvd.cfm?cvename=CVE-2016-10243 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: https://security.gentoo.org/glsa/201709-07 Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users' machines is of utmost importance to us.
