Debian Security Advisory DSA 3503-1 (linux - security update)

Description

Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service, information leak or data loss. CVE-2013-4312 Tetsuo Handa discovered that users can use pipes queued on local (Unix) sockets to allocate an unfair share of kernel memory, leading to denial-of-service (resource exhaustion). This issue was previously mitigated for the stable suite by limiting the total number of files queued by each user on local sockets. The new kernel version in both suites includes that mitigation plus limits on the total size of pipe buffers allocated for each user. CVE-2015-7566 Ralf Spenneberg of OpenSource Security reported that the visor driver crashes when a specially crafted USB device without bulk-out endpoint is detected. Description truncated. Please see the references for more information.
