Red Hat has issued an update for cups. This fixes two vulnerabilities, which can be exploited by malicious people to cause a DoS (Denial of Service).
The vulnerabilities are caused due to a memory leak and a double free error when adding or removing remote shared printers via IPP. This can be exploited to crash the CUPS daemon by e.g. exhausting all available memory or causing memory to be freed twice by sending specially crafted IPP packets to a vulnerable service.
Solution: Updated packages are available via Red Hat Network.
