Description

Multiple integer overflows in the strfmon implementation in the GNU C Library (aka glibc or libc6) 2.10.1 and earlier allow context-dependent attackers to cause a denial of service (memory consumption or application crash) via a crafted format string, as demonstrated by a crafted first argument to the money_format function in PHP, a related issue to CVE-2008-1391.

Note from the SUSE Security Team

This problem requires an attacker to inject strfmon format strings, which is highly unlikely. Also the impact is at most a out of memory situation and would so be spotted. For these reasons we consider these issues minor and will not release fixes at this time.
