Libexif · Libexif · CVE-2020-12767
**Name of the Vulnerable Software and Affected Versions**
libexif version 0.6.21
**Description**
The issue is related to a lack of division by zero checking in the libexif library, which is used for parsing EXIF files. This can lead to a denial of service when exploited. The `exif entry get value` function in `exif-entry.c` is specifically affected by a divide-by-zero error.
**Recommendations**
For libexif version 0.6.21, consider applying a patch or fix that addresses the division by zero error in the `exif entry get value` function. As a temporary workaround, consider restricting the use of the `exif entry get value` function until a patch is available. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
