Description:
According to a iDEFENSE security advisory [0], a command injection
vulnerability exists in the Lynx [2] WWW textual client. 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.
