qmailAdmin is vulnerable to a buffer overflow that could lead to the remote execution of arbitrary code.

2.  Impact Information


qmailAdmin is a free software package that provides a web interface for managing a qmail system with virtual domains.


qmailAdmin fails to properly handle the "PATH_INFO" variable in qmailadmin.c. The PATH_INFO is a standard CGI environment variable filled with user supplied data.


A remote attacker could exploit this vulnerability by sending qmailAdmin a maliciously crafted URL that could lead to the execution of arbitrary code with the permissions of the user running qmailAdmin.

3.  Resolution Information


There is no known workaround at this time.


All qmailAdmin users should upgrade to the latest version:

Code Listing 3.1: Resolution

# emerge --sync
# emerge --ask --oneshot --verbose ">=net-mail/qmailadmin-1.2.10"
