2) Buffer over-read

EUVDB-ID: #VU15166

Risk: Low

CVSSv3.1: 5.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2018-16413

CWE-ID: CWE-125 - Out-of-bounds read

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a heap-based buffer over-read in the MagickCore/quantum-private.h in PushShortPixel() function when called from the coders/psd.c ParseImageResourceBlocks() function. A remote attacker can perform a denial of service attack with a specially crafted image file.

Mitigation

Update the affected package to version: 8:6.9.7.4+dfsg-11+deb9u6.

Vulnerable software versions

imagemagick (Debian package): 8:6.9.7.0+dfsg-1 - 8:6.9.7.4+dfsg-16.1

Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.

Is there known malware, which exploits this vulnerability?

No. We are not aware of malware exploiting this vulnerability.

3) Heap-based buffer overflow

EUVDB-ID: #VU15351

Risk: High

CVSSv3.1: 7.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2018-16642

CWE-ID: CWE-122 - Heap-based Buffer Overflow

Exploit availability: No

Description

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error within InsertRow in coders/cut.c when processing images. A remote attacker can create a specially crafted image, trigger heap-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

Mitigation

Update the affected package to version: 8:6.9.7.4+dfsg-11+deb9u6.

Vulnerable software versions

imagemagick (Debian package): 8:6.9.7.0+dfsg-1 - 8:6.9.7.4+dfsg-16.1

No. We are not aware of malware exploiting this vulnerability.

4) Input validation error

EUVDB-ID: #VU15352

Risk: Low

CVSSv3.1: 4.8 [CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2018-16644

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient check for length in ReadDCMImage() function in coders/dcm.c and in ReadPICTImage() function in coders/pict.c. A remote attacker can pass a specially crafted image to the affected application and trigger application crash.

Mitigation

Update the affected package to version: 8:6.9.7.4+dfsg-11+deb9u6.

Vulnerable software versions

imagemagick (Debian package): 8:6.9.7.0+dfsg-1 - 8:6.9.7.4+dfsg-16.1

Q & A

Can this vulnerability be exploited remotely?

No. This vulnerability can be exploited locally. The attacker should have authentication credentials and successfully authenticate on the system.

Is there known malware, which exploits this vulnerability?

No. We are not aware of malware exploiting this vulnerability.

5) Buffer overflow

EUVDB-ID: #VU15353

Risk: Low

CVSSv3.1: 5.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2018-16645

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description
