Gentoo Linux Security Advisory

Title: 3proxy: Denial of Service (GLSA 200711-13)
Severity: normal
Exploitable: remote
Date: November 08, 2007
Bug(s): #196772
ID: 200711-13

Synopsis

A vulnerability has been discovered in 3proxy, possibly resulting in a Denial of Service.

Background

3proxy is a really tiny cross-platform proxy servers set, including HTTP, HTTPS, FTP, SOCKS and POP3 support.

Affected Packages

Package: net-proxy/3proxy
Vulnerable: < 0.5.3j
Unaffected: >= 0.5.3j
Architectures: All supported architectures


Description

3proxy contains a double free vulnerability in the ftpprchild() function, which frees param->hostname and calls the parsehostname() function, which in turn attempts to free param->hostname again.

Impact

A remote attacker could send a specially crafted request to the proxy, possibly resulting in a Denial of Service. Under typical configuration, the scope of this vulnerability is limited to the local network.

Workaround

There is no known workaround at this time.

Resolution

All 3proxy users should upgrade to the latest version:
Code:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-proxy/3proxy-0.5.3j"
