VULHUB ™

Qpopper is a freely available, open source Post Office Protocol server. It is maintained and distributed by Qualcomm. When popauth is executed with the trace option, it does not correctly handle user-supplied input. A user can supply data to the popauth program through the trace flag which will cause the program to execute shell commands, and follow symbolic links. This problem could be exploited to gain privilege elevation equal to that of the setuid bit on popauth, typically setuid as the pop user.
