Publication date 23 February 2012

Last updated 24 July 2024

Ubuntu priority

Low

Why this priority?

Integer overflow in the vfprintf function in stdio-common/vfprintf.c in glibc 2.14 and other versions allows context-dependent attackers to bypass the FORTIFY_SOURCE protection mechanism, conduct format string attacks, and write to arbitrary memory via a large number of arguments.
