Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
EUVDB-ID: #VU14161
Risk: Low
CVSSv3.1: 5 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H/E:P/RL:O/RC:C]
CVE-ID: CVE-2018-14680
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: No
DescriptionThe vulnerability allows a local attacker to cause DoS condition on the target system.
The vulnerability exists due to the chmd_read_headers() function, as defined in the mspack/chmd.c source code file of the affected software, does not reject blank CHM filenames. A local attacker can submit a CHM file with a blank filename and cause the service to crash.
MitigationUpdate the affected packages.
Opensuse: 15.0

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. However, proof of concept for this vulnerability is available.
EUVDB-ID: #VU14159
Risk: Low
CVSSv3.1: 7.9 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H/E:P/RL:O/RC:C]
CVE-ID: CVE-2018-14681
CWE-ID:
CWE-121 - Stack-based buffer overflow
Exploit availability: No
DescriptionThe vulnerability allows a local attacker to gain elevated privileges on the target system.
The vulnerability exists due to stack-based buffer overflow in the kwajd_read_headers function, as defined in the mspack/kwajd.c source code file. A local attacker can send a specially crafted request that submits malicious input, trigger memory corruption and cause the service to crash or execute arbitrary code with elevated privileges.
Successful exploitation of the vulnerability may result in system compromise.
MitigationUpdate the affected packages.

EUVDB-ID: #VU15374
Risk: Medium
CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2018-15378
CWE-ID:
CWE-125 - Out-of-bounds read
