CVE-2011-1071: Integer Overflow
First published: Mon Feb 28 2011(Updated: )
It was reported [1] that glibc had a bug where it would use alloca() for the length of a user-supplied UTF8 string, times four (with additional integer overflow in the times four). This could lead to an application crash, because alloca() extends the stack. This was reported upstream [2] and subsequently fixed upstream [3].
