Background ========== pstotext is a program that works with GhostScript to extract plain text from PostScript and PDF files. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-text/pstotext < 1.8g-r1 >= 1.8g-r1 Description =========== Max Vozeler reported that pstotext calls the GhostScript interpreter on untrusted PostScript files without specifying the -dSAFER option. Impact ====== An attacker could craft a malicious PostScript file and entice a user to run pstotext on it, resulting in the execution of arbitrary commands with the permissions of the user running pstotext. Workaround ========== There is no known workaround at this time. Resolution ========== All pstotext users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=app-text/pstotext-1.8g-r1" References ========== [ 1 ] Secunia Advisory SA16183 http://secunia.com/advisories/16183/ Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200507-29.xml 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.
