Description

This security bulletin contains information about 2 vulnerabilities.


1) Integer overflow (CVE-ID: CVE-2018-17088)

CWE-ID: CWE-190 - Integer overflow

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber


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)

CWE-ID: CWE-134 - Use of Externally-Controlled Format String

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber


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.
