CVE-2018-17088
Published: 16 September 2018
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 there is an integer overflow during a check for whether a location exceeds the EXIF data length. This is analogous to the CVE-2016-3822 integer overflow in exif.c. This gpsinfo.c vulnerability is unrelated to the CVE-2018-16554 gpsinfo.c vulnerability.
From the Ubuntu Security Team
It was discovered that jhead did not properly handle certain crafted input. If a user were tricked into opening a malicious JPEG file, a remote attacker could cause jhead to crash.
