Summary:<\/p>\n
USN-6844-1 caused the cupsd daemon to never start<\/p>\n
Software Description:
– cups: Common UNIX Printing System(tm)<\/p>\n
Details:<\/p>\n
USN-6844-1 fixed vulnerabilities in the CUPS package. The update
lead to the discovery of a regression in CUPS with regards to
how the cupsd daemon handles Listen configuration directive.
This update fixes the problem.<\/p>\n
We apologize for the inconvenience.<\/p>\n
Original advisory details:
Rory McNamara discovered that when starting the cupsd server with a
Listen configuration item, the cupsd process fails to validate if
bind call passed. An attacker could possibly trick cupsd to perform
an arbitrary chmod of the provided argument, providing world-writable
access to the target.<\/p>\n
