POP3: Qpopper AUTH Overflow (qpop3b.c)
This signature detects attempts to exploit a boundary checking vulnerability in Qualcomm qpopper daemon. Versions 3.0 and higher are susceptible. A successful attack could cause a denial of service, or allow the attacker to execute arbitrary commands on a system with the privileges of the account running the qpop POP3 server.
Extended Description
There is a buffer overflow vulnerability present in current (3.x) versions of Qualcomm popper daemon. These vulnerabilities are remotely exploitable and since the daemon runs as root, the host running qpopper can be completely compromised anonymously. The problem is in pop_msg.c, around line 68 and is the result of vsprintf() or sprintf() calls without bounds checking.
Affected Products
- Qualcomm qpopper 3.0.0
- Qualcomm qpopper 3.0.0 b20
