critical Nessus Plugin ID 191404

Language:

Synopsis

The remote CentOS host is missing one or more security updates for expat.

Description

The remote CentOS Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the expat-2.4.7-1.el9 build changelog.

 - xmlparse.c in Expat (aka libexpat) before 2.4.5 allows attackers to insert namespace-separator characters into namespace URIs. (CVE-2022-25236)

 - In Expat (aka libexpat) before 2.4.5, an attacker can trigger stack exhaustion in build_model via a large nesting depth in the DTD element. (CVE-2022-25313)

 - In Expat (aka libexpat) before 2.4.5, there is an integer overflow in copyString. (CVE-2022-25314)

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

Solution

Update the CentOS 9 Stream expat package.
