<title>exiftags: Multiple vulnerabilities</title> |
| 22 |
<synopsis> |
| 23 |
Multiple vulnerabilities in exiftags possibly allow for the execution of |
| 24 |
arbitrary code or a Denial of Service. |

exiftags is a library and set of tools for parsing, editing and saving |
| 40 |
Exif metadata from images. Exif, the Exchangeable image file format, |
| 41 |
specifies the addition of metadata tags to JPEG, TIFF and RIFF files. |
| 42 |

| 46 |
Meder Kydyraliev (Google Security) discovered that Exif metadata is not |
| 47 |
properly sanitized before being processed, resulting in illegal memory |
| 48 |
access in the postprop() and other functions (CVE-2007-6354). He also |
| 49 |
discovered integer overflow vulnerabilities in the parsetag() and other |
| 50 |
functions (CVE-2007-6355) and an infinite recursion in the readifds() |
| 51 |
function caused by recursive IFD references (CVE-2007-6356). |

<impact type="normal"> |
| 55 |
<p> |
| 56 |
An attacker could entice the user of an application making use of |
| 57 |
exiftags or an application included in exiftags to load an image file |
| 58 |
with specially crafted Exif tags, possibly resulting in the execution |
| 59 |
of arbitrary code with the privileges of the user running the |
| 60 |
application or a Denial of Service. |
| 61 |
</p> |
| 62 |
</impact> |
| 63 |
<workaround> |
| 64 |
<p> |
| 65 |
There is no known workaround at this time. |
| 66 |
</p> |
| 67 |
</workaround> |
| 68 |
<resolution> |
| 69 |
<p> |
| 70 |
All exiftags users should upgrade to the latest version: |
| 71 |
</p> |
| 72 |
<code> |
| 73 |
# emerge --sync |
| 74 |
# emerge --ask --oneshot --verbose ">=media-gfx/exiftags-1.01"</code> |
| 75 |
</resolution> |
