CVE-2013-4511

Status Candidate

Overview

Multiple integer overflows in Alchemy LCD frame-buffer drivers in the Linux kernel before 3.12 allow local users to create a read-write memory mapping for the entirety of kernel memory, and consequently gain privileges, via crafted mmap operations, related to the (1) au1100fb_fb_mmap function in drivers/video/au1100fb.c and the (2) au1200fb_fb_mmap function in drivers/video/au1200fb.c.

Ubuntu Security Notice 2071-1 - Dave Jones and Vince Weaver reported a flaw in the Linux kernel's per event subsystem that allows normal users to enable function tracing. An unprivileged local user could exploit this flaw to obtain potentially sensitive information from the kernel. Stephan Mueller reported an error in the Linux kernel's ansi cprng random number generator. This flaw makes it easier for a local attacker to break cryptographic protections. Various other issues were also addressed.

Mandriva Linux Security Advisory 2013-291

Mandriva Linux Security Advisory 2013-291 - Multiple vulnerabilities has been found and corrected in the Linux kernel. The Linux kernel before 3.12.2 does not properly use the get_dumpable function, which allows local users to bypass intended ptrace restrictions or obtain sensitive information from IA64 scratch registers via a crafted application, related to kernel/ptrace.c and arch/ia64/include/asm/processor.h. The perf_trace_event_perm function in kernel/trace/trace_event_perf.c in the Linux kernel before 3.12.2 does not properly restrict access to the perf subsystem, which allows local users to enable function tracing via a crafted application. Multiple integer overflows in Alchemy LCD frame-buffer drivers in the Linux kernel before 3.12 allow local users to create a read-write memory mapping for the entirety of kernel memory, and consequently gain privileges, via crafted mmap operations, related to the au1100fb_fb_mmap function in drivers/video/au1100fb.c and the au1200fb_fb_mmap function in drivers/video/au1200fb.c. Various other issues have also been addressed.
