CERTFR-2023-AVI-0556

Vulnerability from certfr_avis - Published: - Updated:

De multiples vulnérabilités ont été découvertes dans Splunk SOAR. Elles permettent à un attaquant de provoquer un déni de service à distance, une atteinte à l'intégrité des données et une atteinte à la confidentialité des données.

Solution

Se référer au bulletin de sécurité de l'éditeur pour l'obtention des correctifs (cf. section Documentation).

Splunk SOAR versions antérieures à 6.1.1

Une action supplémentaire est requise si une application spécifie une version de la bibliothèque Python cryptography antérieure à 40.0.0. Celle-ci est expliquée dans l'avis.

CVE-2023-0286 (GCVE-0-2023-0286)

Vulnerability from cvelistv5 – Published: 2023-02-08 19:01 – Updated: 2025-11-04 19:14

Summary

There is a type confusion vulnerability relating to X.400 address processing inside an X.509 GeneralName. X.400 addresses were parsed as an ASN1_STRING but the public structure definition for GENERAL_NAME incorrectly specified the type of the x400Address field as ASN1_TYPE. This field is subsequently interpreted by the OpenSSL function GENERAL_NAME_cmp as an ASN1_TYPE rather than an ASN1_STRING. When CRL checking is enabled (i.e. the application sets the X509_V_FLAG_CRL_CHECK flag), this vulnerability may allow an attacker to pass arbitrary pointers to a memcmp call, enabling them to read memory contents or enact a denial of service. 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.

Vulnerability from cvelistv5 – Published: 2023-02-07 20:54 – Updated: 2025-11-03 21:47

Summary

cryptography is a package designed to expose cryptographic primitives and recipes to Python developers. In affected versions `Cipher.update_into` would accept Python objects which implement the buffer protocol, but provide only immutable buffers. This would allow immutable objects (such as `bytes`) to be mutated, thus violating fundamental rules of Python and resulting in corrupted output. This now correctly raises an exception. This issue has been present since `update_into` was originally introduced in cryptography 1.8.

Severity ?

4.8 (Medium)
