Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
1) Heap-based buffer over-read
EUVDB-ID: #VU12865
Risk: Low
CVSSv3.1: 3.8 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:L/E:U/RL:O/RC:C]
CVE-ID: CVE-2018-5248
CWE-ID:
CWE-126 - Buffer over-read
Exploit availability: No
DescriptionThe 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.
MitigationUpdate the affected package to version: 8:6.9.7.4+dfsg-11+deb9u5
Vulnerable software versionsDebian Linux: All versions
External linkshttp://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
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-2018-11251
CWE-ID:
CWE-125 - Out-of-bounds read
Exploit availability: No
DescriptionThe 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.
MitigationUpdate the affected package to version: 8:6.9.7.4+dfsg-11+deb9u5

3) Out-of-bounds write
EUVDB-ID: #VU13872
Risk: High
CVSSv3.1: 8.3 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2018-12599
CWE-ID:
CWE-787 - Out-of-bounds write
Exploit availability: No
DescriptionThe 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.
