Qpopper Security Vulnerabilities

CVE-1999-0006

Buffer overflow in POP servers based on BSD/Qualcomm's qpopper allows remote attackers to gain root access using a long PASS command.

CVE-1999-0822

Buffer overflow in Qpopper (qpop) 3.0 allows remote root access via AUTH command.

CVE-2000-0096

Buffer overflow in qpopper 3.0 beta versions allows local users to gain privileges via a long LIST command.

CVE-2000-0320

Qpopper 2.53 and 3.0 does not properly identify the \n string which identifies the end of message text, which allows a remote attacker to cause a denial of service or corrupt mailboxes via a message line that is 1023 characters long and ends in \n.

CVE-2000-0442

Qpopper 2.53 and earlier allows local users to gain privileges via a formatting string in the From: header, which is processed by the euidl command.

CVE-2000-1198

qpopper POP server creates lock files with predictable names, which allows local users to cause a denial of service for other users (lack of mail access) by creating lock files for other mail boxes.

CVE-2001-1046

Buffer overflow in qpopper (aka qpop or popper) 4.0 through 4.0.2 allows remote attackers to gain privileges via a long username.

CVE-2001-1068

qpopper 4.01 with PAM based authentication on Red Hat systems generates different error messages when an invalid username is provided instead of a valid name, which allows remote attackers to determine valid usernames on the system.

CVE-2001-1487

popauth utility in Qualcomm Qpopper 4.0 and earlier allows local users to overwrite arbitrary files and execute commands as the pop user via a symlink attack on the -trace file option.

CVE-2002-0454

Qpopper (aka in.qpopper or popper) 4.0.3 and earlier allows remote attackers to cause a denial of service (CPU consumption) via a very large string, which causes an infinite loop.

CVE-2002-0889

Buffer overflow in Qpopper (popper) 4.0.4 and earlier allows local users to cause a denial of service and possibly execute arbitrary code via a long bulldir argument in the user's .qpopper-options configuration file.

CVE-2003-0143

The pop_msg function in qpopper 4.0.x before 4.0.5fc2 does not null terminate a message buffer after a call to Qvsnprintf, which could allow authenticated users to execute arbitrary code via a buffer overflow in a mdef command with a long macro name.

CVE-2003-1452

Untrusted search path vulnerability in Qualcomm qpopper 4.0 through 4.05 allows local users to execute arbitrary code by modifying the PATH environment variable to reference a malicious smbpasswd program.

CVE-2005-3098

poppassd in Qualcomm qpopper 4.0.8 allows local users to modify arbitrary files and gain privileges via the -t (trace file) command line argument.
