Debian Security Advisory DSA-1694-1 security@debian.org

- - ------------------------------------------------------------------------
Package : xterm
Vulnerability : design flaw
Problem type : local (remote)
Debian-specific: no
CVE Id(s) : CVE-2008-2383
Debian Bug : 510030
Paul Szabo discovered that xterm, a terminal emulator for the X Window
System, places arbitrary characters into the input buffer when
displaying certain crafted escape sequences (CVE-2008-2383).
As an additional precaution, this security update also disables font
changing, user-defined keys, and X property changes through escape
sequences.
For the stable distribution (etch), this problem has been fixed in
version 222-1etch3.
For the unstable distribution (sid), this problem will be fixed soon.
We recommend that you upgrade your xterm package.

- - ------------------------------------------------------------------------
Package : xterm
Vulnerability : design flaw
Problem type : local (remote)
Debian-specific: no
CVE Id(s) : CVE-2008-2383
Debian Bug : 510030
The xterm update in DSA-1694-1 disabled font changing as a precaution.
However, users reported that they need this feature. The update in this
DSA makes font shifting through escape sequences configurable, using a
new allowFontOps X resource, and unconditionally enables font changing
through keyboard sequences.
For the stable distribution (etch), this problem has been fixed in
version 222-1etch4.
For the testing distribution (lenny), this problem has been fixed in
version 235-2.
For the unstable distribution (sid), this problem has been fixed in
version 238-2.
We recommend that you upgrade your xterm package.
