"The version of openssl11 installed on the remote host is prior to 1.1.1g-12. It is, therefore, affected by multiple
vulnerabilities as referenced in the ALAS2-2023-1934 advisory.
A timing-based side channel exists in the OpenSSL RSA Decryption implementation, which could be sufficient
to recover a ciphertext across a network in a Bleichenbacher style attack. To achieve a successful
decryption, an attacker would have to be able to send a very large number of trial messages for
decryption. This issue affects all RSA padding modes: PKCS#1 v1.5, RSA-OEAP, and RSASVE. (CVE-2022-4304)
A double-free vulnerability was found in OpenSSL's PEM_read_bio_ex function. The function
PEM_read_bio_ex() reads a PEM file from a BIO and parses and decodes the name (for example,
CERTIFICATE), any header data, and the payload data. If the function succeeds, then the
name_out, header, and data arguments are populated with pointers to
buffers containing the relevant decoded data. The caller is responsible for freeing those buffers.
Constructing a PEM file that results in 0 bytes of payload data is possible. In this case,
PEM_read_bio_ex() will return a failure code but will populate the header argument with a pointer to a
freed buffer. A double-free will occur if the caller also frees this buffer. This will most likely lead to
a crash. This could be exploited by an attacker who can supply malicious PEM files for parsing to achieve
a denial of service attack. (CVE-2022-4450)
A use-after-free vulnerability was found in OpenSSL's BIO_new_NDEF function. The public API function
BIO_new_NDEF is a helper function used for streaming ASN.1 data via a BIO. It is primarily used internally
by OpenSSL to support the SMIME, CMS, and PKCS7 streaming capabilities, but it may also be called directly
by end-user applications. The function receives a BIO from the caller, prepends a new BIO_f_asn1 filter
BIO onto the front of it to form a BIO chain, and then returns the new head of the BIO chain to the
caller. Under certain conditions. For example, if a CMS recipient public key is invalid, the new filter
BIO is freed, and the function returns a NULL result indicating a failure. However, in this case, the BIO
chain is not properly cleaned up, and the BIO passed by the caller still retains internal pointers to the
previously freed filter BIO. If the caller then calls BIO_pop() on the BIO, a use-after-free will occur,
possibly resulting in a crash. (CVE-2023-0215)
A type confusion vulnerability was found in OpenSSL when OpenSSL X.400 addresses processing inside an
X.509 GeneralName. When CRL checking is enabled (for example, 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 cause a denial of service. In most cases, the attack
requires the attacker to provide both the certificate chain and CRL, of which neither needs 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. In this case, this vulnerability is likely
only to affect applications that have implemented their own functionality for retrieving CRLs over a
network. (CVE-2023-0286)
Tenable has extracted the preceding description block directly from the tested product security advisory.
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
