Description
This security bulletin contains information about 3 vulnerabilities.
1) Integer overflow (CVE-ID: CVE-2017-2862)
CWE-ID: CWE-122 - Heap-based Buffer Overflow
CVSSv4: 8.6 [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]
The vulnerability allows a remote attacker to execute arbitrary code on the targeted system.
The weakness exists in the gdk_pixbuf__jpeg_image_load_increment function due to heap-based buffer overflow. A remote attacker can trick the victim to click a malicious link or open a specially crafted JPEG file, trigger memory corruption and execute arbitrary code with privileges of the current user.
Successful exploitation of the vulnerability may result in system compromise.
2) Integer overflow (CVE-ID: CVE-2017-2870)
CWE-ID: CWE-190 - Integer overflow
CVSSv4: 8.6 [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]
The vulnerability allows a remote attacker to execute arbitrary code on the targeted system.
The weakness exists in the tiffimageparse functionality due to integer overflow. A remote attacker can trick the victim to click a malicious link or open a specially crafted TIFF file, trigger heap-based buffer overflow and execute arbitrary code with privileges of the current user.
Successful exploitation of the vulnerability may result in system compromise.
3) NULL pointer dereference (CVE-ID: CVE-2017-6311)
CWE-ID: CWE-476 - NULL Pointer Dereference
CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]
