Jhead · Jhead · CVE-2018-16554
**Name of the Vulnerable Software and Affected Versions**
jhead version 3.00
**Description**
The issue is related to the ProcessGpsInfo function in the gpsinfo.c file, which may allow a remote attacker to cause a denial-of-service attack or unspecified other impact via a malicious JPEG file. This is due to an inconsistency between float and double in a sprintf format string during TAG GPS ALT handling.
**Recommendations**
For jhead version 3.00, as a temporary workaround, consider disabling the ProcessGpsInfo function until a patch is available. Restrict access to handling of TAG GPS ALT to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
