Detail

Synopsis

Multiple vulnerabilities in exiftags possibly allow for the execution of arbitrary code or a Denial of Service.

Background

exiftags is a library and set of tools for parsing, editing and saving Exif metadata from images. Exif, the Exchangeable image file format, specifies the addition of metadata tags to JPEG, TIFF and RIFF files.

Description

Meder Kydyraliev (Google Security) discovered that Exif metadata is not properly sanitized before being processed, resulting in illegal memory access in the postprop() and other functions (CVE-2007-6354). He also discovered integer overflow vulnerabilities in the parsetag() and other functions (CVE-2007-6355) and an infinite recursion in the readifds()
function caused by recursive IFD references (CVE-2007-6356).

Impact

An attacker could entice the user of an application making use of exiftags or an application included in exiftags to load an image file with specially crafted Exif tags, possibly resulting in the execution of arbitrary code with the privileges of the user running the application or a Denial of Service.

Workaround

There is no known workaround at this time.

Resolution

All exiftags users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-gfx/exiftags-1.01"

Title: DSA-1533 exiftags -- insufficient input sanitising
Description: Christian Schmid and Meder Kydyraliev (Google Security) discovered a number of vulnerabilities in exiftags, a utility for extracting EXIF metadata from JPEG images. The Common Vulnerabilities and Exposures project identified the following three problems: Inadequate EXIF property validation could lead to invalid memory accesses if executed on a maliciously crafted image, potentially including heap corruption and the execution of arbitrary code. Flawed data validation could lead to integer overflows, causing other invalid memory accesses, also with the potential for memory corruption or arbitrary code execution. Cyclical EXIF image file directory (IFD) references could cause a denial of service (infinite loop).
