Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
1) Memory corruption
EUVDB-ID: #VU10655
Risk: Low
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-2018-5378
CWE-ID:
CWE-119 - Memory corruption
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to cause DoS condition on the target system.
The weakness exists in the Quagga BGP daemon due to failure to properly bounds check data sent with a NOTIFY to a peer by the Quagga BGP daemon, bgpd. A remote attacker can send specially crafted input and cause the bgpd process or the daemon to crash.
Update the affected packages.
net-misc/quagga to version: 1.2.4
Gentoo 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.
2) Double free memory error
EUVDB-ID: #VU10612
Risk: High
CVSSv3.1: 8.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2018-5379
CWE-ID:
CWE-415 - Double Free
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to cause DoS condition on the target system.
The weakness exists in the Quagga BGP daemon due to double-free memory when processing certain forms of UPDATE message, containing cluster-list and/or unknown attributes. A remote attacker can supply specially crafted input, trigger bqpd to crash and execute arbitrary code.
Update the affected packages.

3) Out-of-bounds read
EUVDB-ID: #VU10617
Risk: Low
CVSSv3.1: 7.1 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2018-5380
CWE-ID:
CWE-125 - Out-of-bounds read
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to obtain potentially sensitive information or cause DoS condition on the target system.
The weakness exists in the Quagga BGP daemon due to out-of-bounds read. A remote attacker send a specially crafted input, overrun internal BGP code-to-string conversion tables used for debug by 1 pointer value and read arbitrary data or cause a denial of service.
Update the affected packages.

Risk: Low
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-2018-5381
CWE-ID:
CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to cause DoS condition on the target system.
The weakness exists in the Quagga BGP daemon due to improper handling of invalid OPEN messages. A remote attacker can trigger infinite loop and cause the service to crash.
Successful exploitation of the vulnerability results in denial of service.
