Discussion

OpenSAML URI Handling Remote Buffer Overflow Vulnerability

OpenSAML is prone to a remote buffer-overflow vulnerability because it fails to perform adequate boundary checks on user-supplied input before copying it to an insufficiently sized buffer.

Attackers can exploit this issue to execute arbitrary code in the context of an application that uses the library. Failed attacks may cause denial-of-service conditions.

Versions prior to OpenSAML 1.1.3 are vulnerable.
