Security Bulletin

This security bulletin contains information about 68 vulnerabilities.

1) Integer underflow

EUVDB-ID: #VU66812

Risk: Low

CVSSv3.1: 7 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:P/RL:O/RC:C]

CVE-ID: CVE-2022-2639

CWE-ID: CWE-191 - Integer underflow

Exploit availability: Yes

Description

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to integer underflow within the reserve_sfa_size() function in the openvswitch kernel module in Linux kernel. A local user can trigger an out-of-bounds read error and crash the system or escalate privileges.


Mitigation

Install update from vendor's website.

CVSSv3.1: 5.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-35252

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to the way curl handles cookies with control codes (byte values below 32). When cookies that contain such control codes are later sent back to an HTTP(S) server, it might make the server return a 400 response, effectively allowing a "sister site" to deny service to siblings.

Exploit availability: No

Description

The vulnerability allows a remote attacker to bypass authentication process.

The vulnerability exists due to an error when processing authentication requests in external authentication plug-ins when more than one of them makes use of deferred authentication replies. A remote attacker can bypass authentication process and gain unauthorized access to the network with only partially correct credentials.

Mitigation

Install update from vendor's website.
