PTeX: Multiple vulnerabilities
Gentoo Linux Security Advisory

All supported architectures
Multiple vulnerabilities were discovered in PTeX, possibly allowing the
execution of arbitrary code or overwriting arbitrary files.
PTeX is a TeX distribution with Japanese support. It is used for
creating and manipulating LaTeX documents.
Multiple issues were found in the teTeX 2 codebase that PTeX builds
upon (GLSA 200709-17, GLSA 200711-26). PTeX also includes vulnerable
code from the GD library (GLSA 200708-05), from Xpdf (GLSA 200709-12,
GLSA 200711-22) and from T1Lib (GLSA 200710-12).
Remote attackers could possibly execute arbitrary code and local
attackers could possibly overwrite arbitrary files with the privileges
of the user running PTeX via multiple vectors, e.g. enticing users to
open specially crafted files.
There is no known workaround at this time.
All PTeX users should upgrade to the latest version:
