    Several vulnerabilities have been discovered in Expat, an XML parsing C     library, which could result in denial of service or potentially the     execution of arbitrary code, if a malformed XML file is processed.

    For the stable distribution (trixie), these problems have been fixed in     version 2.9.0-1~deb13u1.

    We recommend that you upgrade your expat packages.

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

    insufficient entropy, which results in being vulnerable to hash flooding attacks, causing a denial of
    service via crafted XML content. (CVE-2026-76956)

    Update to expat-2.8.3.

Tenable has extracted the preceding description block directly from the Fedora security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

  - Expat through 2.8.3 contains a denial of service vulnerability caused by quadratic algorithmic complexity
    in the storeAtts() function in xmlparse.c, where processing N specified attributes with non-normalized
    values triggers an O(N^2) linear scan of elementType->defaultAtts to determine CDATA status. A remote
    unauthenticated attacker can supply a single well-formed XML document of a few megabytes to an application
    parsing untrusted XML to cause excessive CPU consumption, resulting in denial of service without requiring
    authentication, external entity resolution, or non-default parser options. (CVE-2026-66046)

  - Expat through 2.8.3 contains an out-of-bounds read vulnerability that allows attackers to trigger memory
    corruption by processing XML with external entity parsers created via XML_ExternalEntityParserCreate. A
    struct size mismatch between ELEMENT_TYPE members causes storeAtts to read the attIndex member past
    allocated memory boundaries, resulting in failure to normalize whitespace in non-CDATA attributes or a
    wild pointer dereference causing a segfault. This vulnerability was introduced by the fix for
    CVE-2026-66046. (CVE-2026-76641)

  - In libexpat 2.8.2 and 2.8.3 before 2.8.4, misinterpretation of getentropy's return code leads to
    insufficient entropy, which results in being vulnerable to hash flooding attacks, causing a denial of
    service via crafted XML content. (CVE-2026-76956)

  - libexpat before 2.8.4 lacks handler call depth tracking with custom encoding callbacks. Thus, a use-after-
    free can occur. NOTE: this is similar to CVE-2026-50219, CVE-2026-56131 and CVE-2026-56412.
    (CVE-2026-76957)

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - In libexpat 2.8.2 and 2.8.3 before 2.8.4, misinterpretation of getentropy's return code leads to     insufficient entropy, which results in being vulnerable to hash flooding attacks, causing a denial of     service via crafted XML content. (CVE-2026-76956)

Note that Nessus relies on the presence of the package as reported by the vendor.
