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.

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.
