Synopsis

The remote TencentOS Server 3 host is missing one or more security updates.

Description

Package updates are available for TencentOS Server 3 that fix the following vulnerabilities:

CVE-2024-34459:
An issue was discovered in xmllint (from libxml2) before 2.11.8 and 2.12.x before 2.12.7. Formatting error messages with xmllint --htmlout can result in a buffer over-read in xmlHTMLPrintFileContext in xmllint.c.
