CVE-2009-2847

Publication date 18 August 2009

Last updated 24 July 2024

Ubuntu priority

Low

Why this priority?

The do_sigaltstack function in kernel/signal.c in Linux kernel 2.4 through 2.4.37 and 2.6 before 2.6.31-rc5, when running on 64-bit systems, does not clear certain padding bytes from a structure, which allows local users to obtain sensitive information from the kernel stack via the sigaltstack function.
