Ubuntu Security Notice USN-62-1
18th January, 2005
imagemagick vulnerability
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 4.10
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.
Update instructions
The problem can be corrected by updating your system to the following package version:
- Ubuntu 4.10:
- imagemagick
- libmagick6
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
