Description
This security bulletin contains information about 1 security vulnerability.
1) Security Features (CVE-ID: CVE-2015-1158)
The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
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.
Remediation
Install update from vendor's website.
