AIX : Multiple Vulnerabilities (IJ45059)

high Nessus Plugin ID 174455

Synopsis

The remote AIX host is missing a security patch.

Description

The version of AIX installed on the remote host is prior to APAR IJ45059. It is, therefore, affected by multiple vulnerabilities as referenced in the IJ45059 advisory.

- An issue was discovered in libxml2 before 2.10.3. Certain invalid XML entity definitions can corrupt a hash table key, potentially leading to subsequent logic errors. In one case, a double-free can be provoked. (CVE-2022-40304)

- An issue was discovered in libxml2 before 2.10.3. When parsing a multi-gigabyte XML document with the XML_PARSE_HUGE parser option enabled, several integer counters can overflow. This results in an attempt to access an array at a negative 2GB offset, typically leading to a segmentation fault. (CVE-2022-40303)

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

Solution

Please apply the appropriate interim fix per APAR IJ45059.
