The remote SUSE Linux SUSE15 host has packages installed that are affected by multiple vulnerabilities as referenced in the openSUSE-SU-2022:0178-1 advisory.
In Expat (aka libexpat) before 2.4.3, a left shift by 29 (or more) places in the storeAtts function in xmlparse.c can lead to realloc misbehavior (e.g., allocating too few bytes, or only freeing memory).
(CVE-2021-45960)
In doProlog in xmlparse.c in Expat (aka libexpat) before 2.4.3, an integer overflow exists for m_groupSize. (CVE-2021-46143)
addBinding in xmlparse.c in Expat (aka libexpat) before 2.4.3 has an integer overflow. (CVE-2022-22822)
build_model in xmlparse.c in Expat (aka libexpat) before 2.4.3 has an integer overflow. (CVE-2022-22823)
defineAttribute in xmlparse.c in Expat (aka libexpat) before 2.4.3 has an integer overflow.
(CVE-2022-22824)
lookup in xmlparse.c in Expat (aka libexpat) before 2.4.3 has an integer overflow. (CVE-2022-22825)
nextScaffoldPart in xmlparse.c in Expat (aka libexpat) before 2.4.3 has an integer overflow.
(CVE-2022-22826)
storeAtts in xmlparse.c in Expat (aka libexpat) before 2.4.3 has an integer overflow. (CVE-2022-22827)
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
