Security Bulletin
This security bulletin contains information about 5 vulnerabilities.
1) NULL pointer dereference
EUVDB-ID: #VU6707
Risk: Medium
CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2016-10220
CWE-ID:
CWE-476 - NULL Pointer Dereference
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to NULL pointer dereference error within the gs_makewordimagedevice() function in base/gsdevmem.c. A remote attacker can create a specially crafted PDF file, pass it to the affected application, trigger NULL pointer dereference and crash the application.
Update the affected packages.
Ghostscript: 9.20

5) Type confusion
EUVDB-ID: #VU6546
Risk: Critical
CVSSv3.1: 9.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H/E:H/RL:O/RC:C]
CVE-ID: CVE-2017-8291
CWE-ID:
CWE-704 - Type conversion
Exploit availability: Yes
DescriptionThe vulnerability allows a remote unauthenticated attacker to execute arbitrary commands on a targeted system.
The weakness exists due to type confusion error when processing user-supplied parameters passed to the .rsdparams and .eqproc functions in ghostscript. A remote attacker can submit a specially crafted .eps document, execute code in the context of the ghostscript process and bypass -dSAFER protection.
Successful exploitation of the vulnerability may result in system compromise.
Note: this vulnerability is being exploited in the wild.
Update the affected packages.
