Gentoo: GLSA-200711-13: 3proxy: Denial of Service
Summary
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Gentoo Linux Security Advisory GLSA 200711-13 https://security.gentoo.org/
Severity: Normal Title: 3proxy: Denial of Service Date: November 08, 2007 Bugs: #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 / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-proxy/3proxy < 0.5.3j >= 0.5.3j
========== 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:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-proxy/3proxy-0.5.3j"
References ========= [ 1 ] CVE-2007-5622 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-5622
