Description Laura Pardo 2018-09-18 17:12:17 UTC

A flaw was found in jhead 3.00. The ProcessGpsInfo function of the gpsinfo.c file may allow a remote attacker to cause a denial-of-service attack via a malicious JPEG file, because of inconsistency between float and double in a sprintf format string during TAG_GPS_ALT handling.
