Description:
Josh Bressers has reported a security issue in cvs, which potentially can be exploited by malicious, local users to perform certain actions on a vulnerable system with escalated privileges.
The security issue is caused due to insecure temporary file usage by the cvsbug.in script when saving temporary output to "/tmp" . This may be exploited via symlink attacks to create or overwrite arbitrary files with the privileges of the user invoking the vulnerable script.
The security issue has been reported in version 1.12.12. Other versions may also be affected.
Solution:
Grant only trusted users access to vulnerable systems.
