CVE-2018-16554 low priority: Ubuntu including 1 source packages (jhead), 6 status rows across 6 suites (bionic, cosmic, disco, trusty, upstream, xenial): released 5, not-affected 1.
The ProcessGpsInfo function of the gpsinfo.c file of jhead 3.00 may allow a remote attacker to cause a denial-of-service attack or unspecified other impact via a malicious JPEG file, because of inconsistency between float and double in a sprintf format string during TAG_GPS_ALT handling.
