Background ========== gv is a PostScript and PDF viewer for X which provides a user interface for the ghostscript interpreter. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-text/gv <= 3.5.8-r3 >= 3.5.8-r4 Description =========== gv contains a buffer overflow vulnerability where an unsafe sscanf() call is used to interpret PDF and PostScript files. Impact ====== By enticing a user to view a malformed PDF or PostScript file an attacker could execute arbitrary code with the permissions of the user running gv. Workaround ========== There is no known workaround at this time. All users are encouraged to upgrade to the latest available version of gv.
