cups: incorrect string reference counting (VU#810572)
Published Jun 26, 2015
10.0
HIGHCVSS 2.0
EPSS 29.91%
Description
The add_job function in scheduler/ipp.c in cupsd in CUPS before 2.0.3 performs incorrect free operations for multiple-value job-originating-host-name attributes, which allows remote attackers to trigger data corruption for reference-counted strings via a crafted (1) IPP_CREATE_JOB or (2) IPP_PRINT_JOB request, as demonstrated by replacing the configuration file and consequently executing arbitrary code.
