-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - ------------------------------------------------------------------------ Debian Security Advisory DSA-1694-1 security@debian.org http://www.debian.org/security/ Florian Weimer January 02, 2009 http://www.debian.org/security/faq - ------------------------------------------------------------------------ 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. Upgrade instructions - -------------------- wget url will fetch the file for you dpkg -i file.deb will install the referenced file. If you are using the apt-get package manager, use the line for sources.list as given below: apt-get update will update the internal database apt-get upgrade will install corrected packages You may use an automated update by adding the resources from the footer to the proper configuration.

Debian security update to xterm

Posted Jan 6, 2009 0:20 UTC (Tue) by mikachu (guest, #5333) [Link]

Maybe he read the urxvt manpage?

insecure: boolean
Enables "insecure" mode. Rxvt-unicode offers some escape sequences that echo
arbitrary strings like the icon name or the locale. This could be abused if
somebody gets 8-bit-clean access to your display, whether through a mail
client displaying mail bodies unfiltered or through write(1) or any other
means. Therefore, these sequences are disabled by default. (Note that many
other terminals, including xterm, have these sequences enabled by default,
which doesn't make it safer, though).

You can enable them by setting this boolean resource or specifying -insecure
as an option. At the moment, this enables display-answer, locale, findfont,
icon label and window title requests.
