The remote SUSE Linux SUSE15 host has packages installed that are affected by multiple vulnerabilities as referenced in the openSUSE-SU-2022:0498-1 advisory.

  • Expat (aka libexpat) before 2.4.4 has a signed integer overflow in XML_GetBuffer, for configurations with a nonzero XML_CONTEXT_BYTES. (CVE-2022-23852)

  • Expat (aka libexpat) before 2.4.4 has an integer overflow in the doProlog function. (CVE-2022-23990)

Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
