joernchen of Phenoelit discovered two command injection flaws in Sup, a
console-based email client. An attacker might execute arbitrary command
if the user opens a maliciously crafted email.
For the oldstable distribution (squeeze), these problems have been fixed in
version 0.11-2+nmu1+deb6u1.
For the stable distribution (wheezy), these problems have been fixed in
version 0.12.1+git20120407.aaa852f-1+deb7u1.
We recommend that you upgrade your sup-mail packages.
