------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-print/cups < 1.4.8-r1 >= 1.4.8-r1

Impact

===== A remote attacker may be able to execute arbitrary code using specially crafted streams, IPP requests or files, or cause a Denial of Service (daemon crash or hang). A local attacker may be able to gain escalated privileges or overwrite arbitrary files. Furthermore, a remote attacker may be able to obtain sensitive information from the CUPS process or hijack a CUPS administrator authentication request.

Workaround

There is no known workaround at this time.
