·
Updated

A buffer overflow vulnerability in the function |formatlogline| could allow remote attackers to cause a denial-of-service(DoS) on the affected system (not verified for possible arbitrary code execution). Exploitation of the vulnerability can be triggered when the configuration file |cupsd.conf| sets the value of |loglevel |to |DEBUG|.

Other sources

OpenPrinting CUPS is an open source printing system. In versions 2.4.2 and prior, a heap buffer overflow vulnerability would allow a remote attacker to launch a denial of service (DoS) attack. A buffer overflow vulnerability in the function formatlogline could allow remote attackers to cause a DoS on the affected system. Exploitation of the vulnerability can be triggered when the configuration file cupsd.conf sets the value of loglevel to DEBUG. No known patches or workarounds exist at time of publication.

Ubuntu

OpenPrinting CUPS is vulnerable to a denial of service, caused by improper bounds checking in cupsd when parsing raw files. By persuading a victim to open a specially crafted raw file, a remote attacker could exploit this vulnerability to cause a denial of service.
