Astra Linux – Vulnerability in PHP 7.3

In PHP versions 7.2.x below 7.2.34, 7.3.x below 7.3.23, and 7.4.x below 7.4.11, when AES-CCM mode is used with the opensslencrypt function and a 12-byte IV is provided, only the first 7 bytes of the IV are actually used. This can result in reduced security and incorrect encrypted data...

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 Node.js

Node.js versions that bundle a unpatched version of OpenSSL or run against a dynamically linked version of OpenSSL that is also unpatched are vulnerable to the Marvin attack – https://people.redhat.com/hkario/marvin/. This vulnerability occurs when performing RSA decryption using a private key,...

Astra Linux – Vulnerability in OpenSSL

In addition to the crehash shell command injection identified in CVE-2022-1292, further instances where the crehash script fails to properly sanitize shell metacharacters to prevent command injection were discovered during code reviews. When CVE-2022-1292 was fixed, it wasn’t recognized that ther...

Astra Linux – Vulnerability in OpenSSL

Issue summary: Checking excessively long DH keys or parameters can be very slow. Applications that use functions such as DHcheck, DHcheckex, or EVPPKEYparamcheck to check DH keys or parameters may experience prolonged delays. If the keys or parameters being checked were obtained from an untrusted...

Astra Linux – Vulnerability in OpenSSL

There exists a timing-based side channel in the OpenSSL RSA Decryption implementation. This vulnerability could be sufficient for an attacker to recover plaintext across a network in a Bleichenbacher-style attack. To successfully decrypt data, an attacker would need to be able to send a very larg...

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 PHP 8.1, PHP 7.3

The opensslprivatedecrypt function in PHP, when using PKCS1 padding OPENSSLPKCS1PADDING, which is the default, is vulnerable to the Marvin Attack unless it is used with an OpenSSL version that includes the changes from this pull request: https://github.com/openssl/openssl/pull/13817...

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

The Raccoon attack exploits a flaw in the TLS specification, which allows an attacker to calculate the pre-master secret in connections that use a Diffie-Hellman DH-based ciphersuite. In such cases, the attacker can eavesdrop on all encrypted communications sent over that TLS connection. The atta...

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

To decrypt SM2 encrypted data, an application is expected to call the API function EVPPKEYdecrypt. Typically, an application will call this function twice. The first time, upon entry, the “out” parameter can be NULL, and upon exit, the “outlen” parameter contains the buffer size required to hold...

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...

Astra Linux – Vulnerability in openssl, openssl1.0

ASN.1 strings are internally represented within OpenSSL as an ASN1STRING structure, which contains a buffer for storing the string data and a field for storing the buffer length. This is different from regular C strings, which are represented as a buffer for the string data, terminated with a NUL...

Astra Linux – Vulnerability in OpenSSL

Applications that use non-default options when verifying certificates may be vulnerable to attacks from a malicious Certificate Authority CA to circumvent certain checks. Invalid certificate policies in leaf certificates are silently ignored by OpenSSL, and other certificate policy checks for tho...

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...
