Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) Heap-based buffer overflow
EUVDB-ID: #VU16180
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-2018-12900
CWE-ID:
CWE-122 - Heap-based Buffer Overflow
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to cause DoS condition on the target system.
The vulnerability exists due to heap-based buffer overflow in the cpSeparateBufToContigBuf function in tiffcp.c. A remote unauthenticated attacker can trick the victim into opening a specially crafted TIFF file that can trigger memory corruption and cause the service to crash.
MitigationUpdate the affected packages.
Opensuse: 15.0

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) Out-of-bounds write
EUVDB-ID: #VU15967
Risk: High
CVSSv3.1: 9 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H/E:P/RL:O/RC:C]
CVE-ID: CVE-2018-18557
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 due to decoding of arbitrarily-sized JBIG into a buffer, ignoring the buffer size. A remote unauthenticated attacker can supply specially crafted input, trigger a tif_jbig.c JBIGDecode out-of-bounds write and execute arbitrary code with elevated privileges.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
MitigationUpdate the affected packages.

3) Null pointer dereference
EUVDB-ID: #VU15901
Risk: Low
CVSSv3.1: 3.4 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2018-18661
CWE-ID:
CWE-476 - NULL Pointer Dereference
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to cause DoS condition on the target system.
The vulnerability exists due to NULL pointer dereference in the function LZWDecode in the file tif_lzw.c. A remote attacker can trick the victim into opening a specially crafted input, trigger NULL pointer dereference and cause the service to crash.
MitigationUpdate the affected packages.
