The vulnerabilities could lead to data leakage or memory corruption. Red Hat has released patches to fix these issues. The update is rated with an important security impact and affects multiple Red Hat Enterprise Linux 7 variants.

Multiple security vulnerabilities have been identified in the xorg-x11-server component of Red Hat Enterprise Linux 9, including heap buffer overread/data leakage and use-after-free issues. These vulnerabilities affect the X.Org server, which provides core graphical interface functionality. The issues have been rated with moderate severity by Red Hat Product Security. A security update addressing these vulnerabilities is available and should be applied to affected systems.

Red Hat has issued an important security advisory for the X.Org server in Red Hat Enterprise Linux 7. The update addresses three vulnerabilities: two heap buffer overread/data leakage issues (CVE-2024-31080 and CVE-2024-31081) and one use-after-free vulnerability (CVE-2024-31083). These flaws affect the xorg-x11-server component, which provides core graphical interface functionality. The advisory rates the security impact as important and recommends applying the update after ensuring all prior errata are installed.

A use-after-free vulnerability was found in the ProcRenderAddGlyphs() function of Xorg servers. This issue occurs when AllocateGlyph() is called to store new glyphs sent by the client to the X server, potentially resulting in multiple entries pointing to the same non-refcounted glyphs. Consequently, ProcRenderAddGlyphs() may free a glyph, leading to a use-after-free scenario when the same glyph pointer is subsequently accessed. This flaw allows an authenticated attacker to execute arbitrary code on the system by sending a specially crafted request.
