Package        : ajaxterm
Vulnerability  : weak session IDs
Problem type   : remote
Debian-specific: no
CVE Id(s)      : CVE-2009-1629

It was discovered that ajaxterm, a web-based terminal, generates weak
and predictable session IDs, which might be used to hijack a session or
cause a denial of service attack on a system that uses ajaxterm.

For the oldstable distribution (etch), the problem has been fixed in
version 0.9-2+etch1.

For the stable distribution (lenny), the problem has been fixed in
version 0.10-2+lenny1.

For the unstable distribution (sid), the problem has been fixed in
version 0.10-5.

We recommend that you upgrade your ajaxterm package.
