Red Hat: Security update for HPLIP

Hewlett-Packard Linux Imaging and Printing (HPLIP) provides drivers for Hewlett-Packard (HP) printers and multifunction peripherals. It was found that the HP CUPS (Common UNIX Printing System) fax filter in HPLIP created a temporary file in an insecure way. A local attacker could use this flaw to perform a symbolic link attack, overwriting arbitrary files accessible to a process using the fax filter (such as the hp3-sendfax tool).

Updated packages are available from ftp.redhat.com.

Hewlett-Packard (HP) printers and multifunction peripherals.

It was found that the HP CUPS (Common UNIX Printing System) fax filter in

All users of hplip3 are advised to upgrade to these updated packages, which
contain backported patches to correct these issues.
