    Package : libxml2
    CVE ID : CVE-2023-28484 CVE-2023-29469
    Debian Bug : 1034436 1034437

    Several vulnerabilities were discovered in libxml2, a library providing
    support to read, modify and write XML and HTML files.

    CVE-2023-28484

    A NULL pointer dereference flaw when parsing invalid XML schemas may
    result in denial of service.

    CVE-2023-29469

    It was reported that when hashing empty strings which aren't
    null-terminated, xmlDictComputeFastKey could produce inconsistent
    results, which may lead to various logic or memory errors.

    For the stable distribution (bullseye), these problems have been fixed in version 2.9.10+dfsg-6.7+deb11u4.

    We recommend that you upgrade your libxml2 packages.

    For the detailed security status of libxml2 please refer to its security tracker page at:
    https://security-tracker.debian.org/tracker/libxml2
