AI-suggested
To mitigate CVE-2024-33904, organizations should first verify if they are running Hyprland versions up to 0.39.1 and plan to upgrade to versions including the fix after commit 28c8561 once available. In the absence of an official patch, administrators can implement the following measures: 1) Restrict local user access to trusted personnel only, minimizing the risk of local exploitation. 2) Employ mandatory access controls (e.g., SELinux, AppArmor) to limit Hyprland's ability to write or execute code from temporary directories. 3) Monitor and audit temporary file creation and access patterns for suspicious activity indicative of race condition exploitation. 4) Use filesystem permissions and mount options (e.g., noexec on /tmp) to reduce the risk of executing malicious code from temporary files. 5) Encourage users to avoid running untrusted code or scripts locally. 6) Stay informed on Hyprland updates and apply patches promptly once released. These targeted mitigations go beyond generic advice by focusing on controlling local access, filesystem security, and monitoring specific to the nature of this race condition vulnerability.
Description
In plugins/HookSystem.cpp in Hyprland through 0.39.1 (before 28c8561), through a race condition, a local attacker can cause execution of arbitrary assembly code by writing to a predictable temporary file.
