Synopsis

The remote EulerOS host is missing multiple security updates.

Description

According to the versions of the expat package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

 - 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)

 - 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)
