Details

Paul Szabo discovered that the DECRQSS escape sequences were not handled
correctly by xterm. Additionally, window title operations were also not
safely handled. If a user were tricked into viewing a specially crafted
series of characters while in xterm, a remote attacker could execute
arbitrary commands with user privileges. (CVE-2006-7236, CVE-2008-2382)
