Astra Linux – Vulnerability in openssl1.0

In situations where an attacker receives automated notifications of the success or failure of a decryption attempt, an attacker can recover the CMS/PKCS7 transport encryption key after sending a very large number of messages to be decrypted. They can also decrypt any RSA-encrypted message encrypt...

Astra Linux – Vulnerability in OpenSSL

AES OCB mode for 32-bit x86 platforms, using the AES-NI assembly-optimized implementation, may not encrypt all of the data under certain circumstances. This could reveal sixteen bytes of data that were already present in the memory but were not written. In the special case of “in-place” encryptio...

Astra Linux – Vulnerability in OpenSSL

Issue summary: Generating excessively long X9.42 DH keys or checking overly long X9.42 DH keys or parameters can be very slow. Applications that use functions like DHgeneratekey to generate an X9.42 DH key may experience prolonged delays. Similarly, applications that use functions like...

Astra Linux – Vulnerability in openssl1.0

Calls to the EVPCipherUpdate, EVPEncryptUpdate, and EVPDecryptUpdate functions may cause the output length argument to overflow in some cases where the input length is close to the maximum permissible length for integers on the platform. In such cases, the return value from the function call will...

Astra Linux – Vulnerability in OpenSSL

The public API function BIOnewNDEF is a helper function used for streaming ASN.1 data via a BIO. It is primarily used internally by OpenSSL to support SMIME, CMS, and PKCS7 streaming capabilities. However, it can also be called directly by end-user applications. This function receives a BIO from...

Astra Linux – Vulnerability in openssl1.0

Normally, in OpenSSL, EC groups always contain a co-factor, and this co-factor is used in code paths that resist side channels. However, in some cases, it is possible to create a group using explicit parameters instead of a named curve. In these cases, the group may not contain a co-factor. This...

Astra Linux – Vulnerability in openssl1.0

The X.509 GENERALNAME type is a generic type used to represent various types of names. One of these name types is known as EDIPARTYNAME. OpenSSL provides a function called GENERALNAMEcmp, which compares different instances of a GENERALNAME to determine whether they are equal. This function behave...

Astra Linux – Vulnerability in OpenSSL

Issue summary: Processing some specially crafted ASN.1 object identifiers or data containing them may be very slow. Impact summary: Applications that use OBJobj2txt directly, or use any of the OpenSSL subsystems such as OCSP, PKCS7/SMIME, CMS, CMP/CRMF, or TS without a message size limit may...

Astra Linux – Vulnerability in OpenSSL

A security vulnerability has been identified in all supported versions of OpenSSL, related to the verification of X.509 certificate chains that include policy constraints. Attackers may be able to exploit this vulnerability by creating a malicious certificate chain that triggers exponential use o...
