Security Bulletin

This security bulletin contains information about 4 vulnerabilities.

1) Heap-based buffer over-read

EUVDB-ID: #VU12865

Risk: Low

CVSSv4.0: 1 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2018-5248

CWE-ID: CWE-126 - Buffer over-read

Exploit availability: No

Description

The vulnerability allows a remote attacker to cause DoS condition on the target system.

The weakness exists in coders/sixel.c in the ReadSIXELImage function, related to the sixel_decode function, due to heap-based buffer over-read. A remote attacker can trick the victim into opening a specially crafted file, trigger memory corruption and cause the service to crash.

Mitigation

Update the affected package to version: 8:6.9.7.4+dfsg-11+deb9u5

Vulnerable software versions

Debian Linux: All versions

CPE2.3 External links

https://www.debian.org/security/2018/dsa-4245


Q & A

Can this vulnerability be exploited remotely?

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.

2) Buffer over-read

EUVDB-ID: #VU13581

Risk: Low

CVSSv4.0: 4 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2018-11251

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 heap-based buffer over-read in ReadSUNImage in coders/sun.c, which allows attackers to cause a denial of service (application crash in SetGrayscaleImage in MagickCore/quantize.c) via a specially crafted SUN image file. A remote attacker can perform a denial of service attack.

Mitigation

Update the affected package to version: 8:6.9.7.4+dfsg-11+deb9u5

Vulnerable software versions

Debian Linux: All versions

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

3) Out-of-bounds write

EUVDB-ID: #VU13872

Risk: High

CVSSv4.0: 5.7 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]

CVE-ID: CVE-2018-12599

CWE-ID: CWE-787 - Out-of-bounds write

Exploit availability: No

Description

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

The vulnerability exists in ReadBMPImage and WriteBMPImage in coders/bmp.c due to out-of-bounds write. A remote unauthenticated attacker can trick the victim into opening a specially crafted file and execute arbitrary code with elevated privileges.

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+deb9u5
