Security Bulletin
This security bulletin contains information about 5 vulnerabilities.
1) NULL pointer dereference
EUVDB-ID: #VU6707
Risk: Medium
CVSSv4.0: 6.6 [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/E:U/U:Green]
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

4) NULL pointer dereference
EUVDB-ID: #VU6709
Risk: Medium
CVSSv4.0: 6.6 [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/E:U/U:Green]
CVE-ID: CVE-2017-7207
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 a NULL pointer dereference error within the mem_get_bits_rectangle() function in base/gdevmem.c in Ghostscript. A remote attacker can create a specially crafted PostScript file, pass it to the affected application and crash it.
Update the affected packages.

5) Type confusion
EUVDB-ID: #VU6546
Risk: Critical
CVSSv4.0: 9.3 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:A/U:Red]
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.
