Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- 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. (CVE-2023-0286)

Solution

Update the openssl-1.0.1g library and its related packages to version 1.0.1g+e1 or later.
