Details

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.
