Summary

Here are the details from the Slackware 15.0 ChangeLog: extra/tigervnc/tigervnc-1.12.0-i586-7_slack15.0.txz: Rebuilt. Recompiled against xorg-server-1.20.14, including a patch for a security issue: By providing a modified bitmap, a heap-based buffer overflow may occur. This may lead to local privilege escalation if the server is run as root or remote code execution (e.g. x11 over ssh). This vulnerability was discovered by: Jan-Niklas Sohn working with Trend Micro Zero Day Initiative For more information, see: https://lists.x.org/archives/xorg-announce/2024-October/003545.html https://www.cve.org/CVERecord?id=CVE-2024-9632 (* Security fix *)
