PTeX: Multiple vulnerabilities Multiple vulnerabilities were discovered in PTeX, possibly allowing the execution of arbitrary code or overwriting arbitrary files. ptex 2008-05-12 2008-05-12 196673 remote 3.1.10_p20071203 3.1.10_p20071203

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:
