Security Bulletin

This security bulletin contains information about 19 vulnerabilities.

1) Processor optimization removal or modification of security-critical code

EUVDB-ID: #VU65205

Risk: Low

CVSSv3.1:

CVE-ID: CVE-2022-29900

CWE-ID: CWE-1037 - Processor optimization removal or modification of security-critical code

Exploit availability: No

Description

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

The vulnerability exists due to a mistrained branch predictions for return instructions. A local user can execute arbitrary speculative code under certain microarchitecture-dependent conditions. The vulnerability was dubbed  RETbleed.

Mitigation

Install update from vendor's website.

2) Heap-based buffer overflow

EUVDB-ID: #VU62830

Risk: High

CVSSv3.1:

CVE-ID: CVE-2022-24903

CWE-ID: CWE-122 - Heap-based Buffer Overflow

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform a denial of service or potentially execute arbitrary code on the target system.

The vulnerability exists due to a boundary error when parsing data in imtcp, imptcp, imgssapi, and imhttp modules used for TCP syslog reception. A remote attacker can pass specially crafted data to the application, trigger heap-based buffer overflow and cause a denial of service or potentially execute arbitrary code on the target system.

Successful exploitation of this vulnerability is possible if the attacker is able to directly send specially crafted messages to the rsyslog daemon or by injecting specially crafted data into log files. Vulnerability exploitation in the second scenario requires that the rsyslog client supports octet-counted framing, which is not a default configuration.

Mitigation

Install update from vendor's website.

3) Missing Encryption of Sensitive Data

EUVDB-ID: #VU64922

Risk: Low

CVSSv3.1:

CVE-ID: CVE-2022-2097

Exploit availability: No

Description

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to an error in AES OCB mode for 32-bit x86 platforms using the AES-NI assembly optimized implementation. Under specific circumstances OpenSSL does not encrypt the entire message and can reveal sixteen bytes of data that was preexisting in the memory that wasn't written. A remote attacker can gain access to potentially sensitive information.

Exploit availability: No

Description

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

The vulnerability exists due to insecure processing of compressed HTTP responses.
