Exiv2 · Exiv2 · CVE-2021-37615
**Name of the Vulnerable Software and Affected Versions**
Exiv2 versions v0.27.4 and earlier
**Description**
A null pointer dereference was found in Exiv2, which can be triggered when printing the metadata of a crafted image file. This can potentially be exploited by an attacker to cause a denial of service if they can trick the victim into running Exiv2 on a crafted image file. The bug is only triggered when printing the interpreted (translated) data, which requires an extra command line option (`-p t` or `-P t`).
**Recommendations**
For Exiv2 versions v0.27.4 and earlier, update to version v0.27.5 to resolve the issue. As a temporary workaround, consider avoiding the use of the `-p t` or `-P t` command line options to minimize the risk of exploitation.
