REDHAT-BUG-789936
First published: Mon Feb 13 2012(Updated: )
An insufficient escape sequences sanitization flaw was found in the way xpdf, a PDF file viewer for the X window system, and poppler, a PDF rendering library, performed sanitization of certain characters to be displayed in the error messages, which arose during presentation of certain PDF files. A remote attacker could use this flaw to modify a window's title, or, possibly execute arbitrary commands or overwrite files, via a specially-crafted PDF file containing an escape sequence for a terminal emulator if local, unsuspecting user opened such crafted PDF file in xpdf or in an application linked against poppler library (for example evince).
