Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) Out-of-bounds read
EUVDB-ID: #VU6887
Risk: Low
CVSSv3.1: 4.2 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:N/I:N/A:L/E:P/RL:O/RC:C]
CVE-ID: CVE-2017-8310
CWE-ID:
CWE-125 - Out-of-bounds read
Exploit availability: Yes
DescriptionThe vulnerability allows a remote attacker to perform denial of service attack.
The vulnerability exists due to boundary error in CreateHtmlSubtitle in VideoLAN VLC, when processing subtitles. A remote unauthenticated attacker can create a specially crafted subtitle, trick the victim into loading it and trigger application crash via out-of-bounds read. MitigationUpgrade to 2.2.6-1.
Vulnerable software versionsArch Linux: All versions

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. However, proof of concept for this vulnerability is available.
2) Heap-based buffer overflow
EUVDB-ID: #VU6673
Risk: High
CVSSv3.1: 8.6 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H/E:P/RL:O/RC:C]
CVE-ID: CVE-2017-8311
CWE-ID:
CWE-122 - Heap-based Buffer Overflow
Exploit availability: Yes
DescriptionThe vulnerability allows a remote unauthenticated attacker to execute arbitrary code and take over the device.
The weakness exists due to a boundary error in ParseJSS in VideoLAN VLC when processing subtitles. A remote attacker can create specially crafted subtitle file, which when loaded by the target user with the help of affected software leads to arbitrary code execution.
Successful exploitation of the vulnerability may result in full control over the affected PC.
MitigationUpgrade to 2.2.6-1.
