The vulnerability could allow attackers to execute arbitrary commands with the privileges of the underlying user. The problem specifically exists within the feature to execute local "cgi-bin" programs via the "lynxcgi:" URI handler. The Common Vulnerabilities and Exposures (CVE) project assigned the id CVE-2005-2929 [3] to the problem. Additionally, according to a security advisory from Ulf Harnhammar [1], a stack-based buffer overflow in the "HTrjis" function in Lynx allows remote NNTP servers to execute arbitrary code via certain article headers containing Asian characters that cause Lynx to add extra escape (ESC) characters. The Common Vulnerabilities and Exposures (CVE) project assigned the id CVE-2005-3120 [4] to the problem. ________________________________________________________________________ References: [0] http://www.idefense.com/application/poi/display?id=338 [1] http://lists.grok.org.uk/pipermail/full-disclosure/2005-October/038019.html [2] http://lynx.isc.org/ [3] http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2005-2929 [4] http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2005-3120 ________________________________________________________________________ For security reasons, this advisory was digitally signed with the OpenPGP public key "OpenPKG <openpkg@xxxxxxxxxxx>" (ID 63C4CB9F) of the OpenPKG project which you can retrieve from http://pgp.openpkg.org and hkp://pgp.openpkg.org.
