The vulnerability of the GENERAL_NAME_cmp function in the OpenSSL library, which allows a hacker to trigger a denial-of-service attack

The vulnerability of the GENERALNAMEcmp function in the OpenSSL library is related to the lack of a mechanism for data type conversion during the processing of x400 addresses. Exploiting this vulnerability could allow an attacker to cause service interruptions remotely...

Oracle Essbase (Jan 2023 CPU)

The version of Oracle Essbase installed on the remote host is missing a security patch from the January 2023 Critical Patch Update CPU. It is, therefore, affected by multiple vulnerabilities, including: - Vulnerability in Oracle Essbase component: Essbase Web Platform OpenSSL. The supported versi...

Impact of OpenSSL Vulnerabilities Advisory Released On February 7, 2023

OpenSSL has released a security advisory to address multiple vulnerabilities affecting OpenSSL versions 3.0, 1.1.1, and 1.0.2.CVE-2023-0286 - X.400 address type confusion in X.509 GeneralNameCVE-2022-4304 - Timing Oracle in RSA DecryptionCVE-2022-4203 - X.509 Name Constraints Read Buffer...

Type Confusion

openssl is vulnerable to type confusion. The vulnerability exists because it may allow an attacker to pass arbitrary pointers to a memcmp call, enabling them to read memory content...

Denial Of Service (DoS)

openssl is vulnerable to Denial Of Service DoS. The vulnerability exists because if a recipe cms recipient public key is invalid, the new filter bio is freed and the function returns a NULL result indicating a failure The public API function BIOnewNDEF is a helper function used for streaming ASN....

GHSA-QF87-Q4GG-CG43 bottlerocket dependency openssl is vulnerable to dereferenced null pointers

A null pointer in OpenSSL can be dereferenced when signatures are being verified in malformed PKCS7 data. Agents or clients compiled with OpenSSL may experience unexpected crashes. OpenSSL has been removed in bottlerocket/update-operator version 1.1.0 in favor of Rust-based TLS using rustls...

bottlerocket dependency openssl has a double free vulnerability

A timing based side channel exists in the OpenSSL RSA decryption implementation which could enable a recovery of plaintext from across the network. This affects all RSA padding modes. A server agent compiled with OpenSSL could be made to give up plaintext payloads over the network, but this would...

GHSA-3WXX-JXWC-MG39 bottlerocket dependency openssl has a double free vulnerability

A double-free vulnerability exists in OpenSSL where it is possible to construct a malicious PEM file that has 0 bytes of payload data. This then points to data that has already been freed in memory which, when freed again, leads to a crash. Agents or clients compiled with OpenSSL may crash...

bottlerocket dependency openssl is vulnerable to read buffer overflow via X.509 verification

A read buffer overflow can be triggered in OpenSSL X.509 verification during name constraint checking. Note that this occurs after the certificate chain has been verified and would require a compromised CA. This can cause a client or agent compiled with OpenSSL to crash unexpectedly. OpenSSL has...

Note that this occurs after the certificate chain has been verified and would require a compromised CA. This can cause a client or agent compiled with OpenSSL to crash unexpectedly. OpenSSL has...

bottlerocket dependency openssl provides streaming of ASN.1 data via a BIO

An OpenSSL public API provides streaming of ASN.1 data via a BIO. It is possible for a malicious third party to use the BIO to access unfreed memory pointers that are not cleaned up after execution of the API. Freeing these memory pointers will result in a crash. Agents and clients compiled with...

It is possible for a malicious third party to use the BIO to access unfreed memory pointers that are not cleaned up after execution of the API. Freeing these memory pointers will result in a crash. Agents and clients compiled with...

Denial Of Service (DoS)

openssl is vulnerable to Denial Of Service DoS. The vulnerability exists in the PEMreadbioex because if the caller also frees this buffer then a double free will occur which will most likely lead to a crash where it can be exploited by an attacker who has the ability to supply malicious PEM files...
