The vulnerability exists due to infinite loop within the BN_mod_sqrt() function when processing an ASN.1 certificate that contains elliptic curve public keys in compressed form or explicit elliptic curve parameters with a base point encoded in compressed form. A remote attacker can supply a specially crafted certificate to the TLS server or client, consume all available system resources and cause denial of service conditions.

26) Heap-based buffer overflow

EUVDB-ID: #VU62830

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-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.

CVE-ID: CVE-2022-40674

CWE-ID: CWE-416 - Use After Free

Exploit availability: No

Description

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error in the doContent() function in xmlparse.c. A remote attacker can pass specially crafted input to the application that is using the affected library, trigger a use-after-free error and execute arbitrary code on the system.

32) Type Confusion

Risk: High

CVSSv3.1: 7.9 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-0286

CWE-ID: CWE-843 - Type confusion

Exploit availability: No

Description

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

The vulnerability exists due to a type confusion error related to X.400 address processing inside an X.509 GeneralName. A remote attacker can pass specially crafted data to the application, trigger a type confusion error and perform a denial of service (DoS) attack or read memory contents.

In most cases, the attack requires the attacker to provide both the certificate chain and CRL, neither of which need to have a valid signature. If the attacker only controls one of these inputs, the other input must already contain an X.400 address as a CRL distribution point, which is uncommon. As such, this vulnerability is most likely to only affect applications which have implemented their own functionality for retrieving CRLs over a network.
