| Severity: | normal |
| Title: | exiftags: Multiple vulnerabilities |

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.
Affected packages
| Package | Vulnerable | Unaffected | Architecture(s) |
|---|---|---|---|
| media-gfx/exiftags | < 1.01 | >= 1.01 | All supported architectures |
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"
