    Package        : raptor2
    Version        : 2.0.14-1.2+deb11u1
    CVE ID         : CVE-2024-57822 CVE-2024-57823


    Two issues have been found in raptor2, an RDF parser and serializer
    utilities. One issue is related to a heap-based buffer over-read when
    parsing triples. The other issue is related to an integer underflow when
    normalizing an URI.



    For Debian 11 bullseye, these problems have been fixed in version
    2.0.14-1.2+deb11u1.

    We recommend that you upgrade your raptor2 packages.

    For the detailed security status of raptor2 please refer to
    its security tracker page at:
