=========================================================== Ubuntu Security Notice USN-62-1 January 18, 2005 imagemagick vulnerability CAN-2005-0005 =========================================================== A security issue affects the following Ubuntu releases: Ubuntu 4.10 (Warty Warthog) The following packages are affected: imagemagick libmagick6 The problem can be corrected by upgrading the affected package to version 5:6.0.2.5-1ubuntu1.3. In general, a standard system upgrade is sufficient to effect the necessary changes. Details follow: Andrei Nigmatulin discovered a potential buffer overflow in the PhotoShop Document image decoding function of ImageMagick. Decoding a malicious PSD image which specifies more than the allowed 24 channels might result in execution of arbitrary code with the user's privileges. Since ImageMagick can be used in custom printing systems, this also might lead to privilege escalation (execute code with the printer spooler's privileges). However, Ubuntu's standard printing system does not use ImageMagick, thus there is no risk of privilege escalation in a standard installation.
