Alpine: multiple qt6-qtwebengine packages: security update to 6.8.3-r5

high Tenable Cloud Security Plugin ID 435882

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

- A flaw was found in libxml2's xmlBuildQName function, where integer overflows in buffer size calculations
can lead to a stack-based buffer overflow. This issue can result in memory corruption or a denial of
service when processing crafted input. (CVE-2025-6021)

- Insufficient validation of untrusted input in Core in Google Chrome prior to 139.0.7258.66 allowed a
remote attacker to spoof the contents of the Omnibox (URL bar) via a crafted HTML page. (Chromium security
severity: Low) (CVE-2025-8582)

- libxml2 before 2.12.10 and 2.13.x before 2.13.6 has a stack-based buffer overflow in xmlSnprintfElements
in valid.c. To exploit this, DTD validation must occur for an untrusted document or untrusted DTD. NOTE:
this is similar to CVE-2017-9047. (CVE-2025-24928)
