REDHAT-BUG-1084577
First published: Fri Apr 04 2014(Updated: )
It was reported that ANSI escape sequences could be added to printer names in CUPS. Becaue CUPS has a browsing feature that, when enabled, allows remote hosts to announce shared printers, a malicious host or user could send a specially-crafted UDP packet to a CUPS server announcing an arbitrary printer name that includes ANSI escape sequences. Since the CUPS daemon does not remove these characters, a user on the targeted system could query the printer list (using 'lpstat -a', for example). If this were done in a terminal that supported the ANSI escape sequences (like a terminal with support for color), then code execution could be possible as the terminal would interpret the ANSI escape sequences contained in the printer name.
