Vulnerabilities

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.

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.

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.

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 c…

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.

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.

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

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…

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.

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 cha…

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.

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

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

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