Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
EUVDB-ID: #VU15789
Risk: Low
CVSSv3.1: 3.9 [CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:L/I:L/A:L/E:U/RL:O/RC:C]
CVE-ID: CVE-2018-19044
CWE-ID:
CWE-61 - UNIX Symbolic Link (Symlink) Following
Exploit availability: No
DescriptionThe vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a symlink following issue when writing data to a temporary file upon a call to PrintData or PrintStats. A local user can create a specially crafted symbolic link to a critical file on the system and overwrite it with privileges of the application, if fs.protected_symlinks is set to 0.
Successful exploitation of this vulnerability may result in privilege escalation.
MitigationUpdate the affected packages.
sys-cluster/keepalived to version: 2.0.10
Gentoo Linux: All versions

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.
EUVDB-ID: #VU15790
Risk: Low
CVSSv3.1: 2.9 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2018-19045
CWE-ID:
CWE-264 - Permissions, Privileges, and Access Controls
Exploit availability: No
DescriptionThe vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to software sets insecure default permissions (0666) when creating new temporary files upon a call to PrintData or PrintStats. A local user can read potentially sensitive information from temporary files.
Update the affected packages.

CVSSv3.1: 3.5 [CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2018-19046
CWE-ID:
CWE-264 - Permissions, Privileges, and Access Controls
Exploit availability: No
DescriptionThe vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to software does not check for existing plain files when writing data to a temporary file upon a call to PrintData or PrintStats. A local user can create a file "/tmp/keepalived.data" or "/tmp/keepalived.stats" with read access to it for the attacker and write access for keepalived process, it is possible to gain access to sensitive information, written into these files by the application.
Update the affected packages.

EUVDB-ID: #VU15792
Risk: High
CVSSv3.1: 8.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2018-19115
CWE-ID:
CWE-122 - Heap-based Buffer Overflow
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when parsing HTTP status codes within the extract_status_code() function in lib/html.c. A remote attacker can send a specially crafted HTTP request, trigger heap-based buffer overflow and peform denial of service attack or execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
MitigationUpdate the affected packages.
