Description:
Imran Ghory has reported a vulnerability in Pine, which potentially can be exploited by malicious, local users to perform certain actions on a vulnerable system with escalated privileges.
The vulnerability is caused due to a race condition in the rpdump utility when creating files. The problem is that there is a larger gap between the time that a check is made to determine whether a local file exists and the time that the file is created. This can be exploited via symlink attacks to overwrite arbitrary files with the privileges of the user running the vulnerable program.
Successful exploitation requires write permissions to the directory, which rpdump creates the local file in.
The vulnerability has been reported in Pine 4.62. Other versions may also be affected.
