CVE-2011-2516: Apache Santuario XML Security for C++ contains buffer
overflows signing or verifying with large keys.
Vendor: The Apache Software Foundation
Versions Affected: Apache Santuario XML Security for C++ library versions
prior to V1.6.1
Description: A buffer overflow exists when creating or verifying XML
with RSA keys of sizes on the order of 8192 or more bits. This typically
in a crash and denial of service in applications that verify signatures
keys that could be supplied by an attacker.
Mitigation: Applications using library versions older than V1.6.1 should
as soon as possible. Distributors of older versions should apply the
from this subversion revision:
Applications that can prevent the use of arbitrary keys supplied by an
(such as within the ds:KeyInfo element of a signature), or limit key
prevent the exploitation of this bug.
