Lynx .mailcap and .mime.type code execution

lynx-mailcap-mimetype-code-execution (46132)

Description:

Lynx could allow a local attacker to execute arbitrary code on the system, caused by the processing of .mailcap and .mime.type files in the current directory. By persuading a victim to run Lynx in a specially-crafted file in the directory, a local attacker could exploit this vulnerability to execute arbitrary code on the system with the privileges of the victim.
