Bug ID: 17680
Summary: Unbounded alloca in vfprintf related to format
specifiers (CVE-2012-3406)
Product: glibc
Version: 2.21
URL: https://bugzilla.redhat.com/show_bug.cgi?id=826943
Status: NEW
Severity: normal
Priority: P2
Component: stdio
Assignee: fweimer at redhat dot com
Reporter: fweimer at redhat dot com
Flags: security+
Created attachment 7997
--> https://sourceware.org/bugzilla/attachment.cgi?id=7997&action=edit
glibc-rh841318.patch
A large number of format specifiers could result in a stack overflow in
vfprintf due to an unbounded alloca call.
I'm attaching the current Fedora version of the patch. I will try to reduce
the size of the included test case before submitting it.
