Description
This security bulletin contains information about 2 secuirty vulnerabilities.
1) Integer overflow (CVE-ID: CVE-2018-17088)
The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
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.
2) Format string error (CVE-ID: CVE-2018-16554)
The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
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.
