Several buffer overflow vulnerabilities in ImageMagick were discovered by Marcus Meissner from SUSE. These vulnerabilities would allow an attacker to create a malicious image or video file in AVI, BMP, or DIB formats which could crash the reading process. It may be possible to create malicious images that could also allow for the execution of arbitrary code with the privileges of the invoking user or process.

The updated packages provided are patched to correct these problems.

Updated ImageMagick packages that fix various security vulnerabilities are now available.

ImageMagick(TM) is an image display and manipulation tool for the X Window System.

A heap overflow flaw was discovered in the ImageMagick image handler.
An attacker could create a carefully crafted BMP file in such a way that it would cause ImageMagick to execute arbitrary code when processing the image. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2004-0827 to this issue.

A temporary file handling bug has been found in ImageMagick's libmagick library. A local user could overwrite or create files as a different user if a program was linked with the vulnerable library.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2003-0455 to this issue.

Users of ImageMagick should upgrade to these updated packages, which contain a backported patch, and is not vulnerable to this issue.

Marcus Meissner discovered that ImageMagick's BMP decoder would crash when loading the test BMP file created by Chris Evans for testing the previous Qt vulnerability.

Updated ImageMagick packages that fixes a buffer overflow are now available.

ImageMagick(TM) is an image display and manipulation tool for the X Window System.

A buffer overflow flaw was discovered in the ImageMagick image handler. An attacker could create a carefully crafted image file with an improper EXIF information in such a way that it would cause ImageMagick to execute arbitrary code when processing the image. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2004-0981 to this issue.

David Eisenstein has reported that our previous fix for CVE-2004-0827, a heap overflow flaw, was incomplete. An attacker could create a carefully crafted BMP file in such a way that it could cause ImageMagick to execute arbitrary code when processing the image. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2004-0827 to this issue.

Users of ImageMagick should upgrade to these updated packages, which contain a backported patch, and is not vulnerable to this issue.

Updated ImageMagick packages that fix a BMP loader vulnerability are now available.

Marcus Meissner from SUSE has discovered several buffer overflows in the ImageMagick graphics library. An attacker could create a malicious image or video file in AVI, BMP, or DIB format that could crash the reading process. It might be possible that carefully crafted images could also allow to execute arbitrary code with the capabilities of the invoking process.

Markus Meissner discovered several potential buffer overflows in some image decoding functions of ImageMagick. Decoding a malicious BMP or DIB image or AVI video 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.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
