Astra Linux – Vulnerability in OpenSSL

Issue summary: An application attempting to decrypt messages encrypted using password-based encryption in CMS can trigger an out-of-bounds read and write attack. Impact summary: This out-of-bounds read attack may cause a system crash, leading to a denial of service for the application. The...

Astra Linux – Vulnerability in OpenSSL

Issue summary: A uncommon configuration where clients perform DANE TLSA-based server authentication, combined with unusual server DANE TLSA records, may lead to a use-after-free or double-free on the client side. Impact summary: A use-after-free can have various potential consequences, such as th...

Astra Linux – Vulnerability in OpenSSL

Issue summary: When processing a delta CRL that contains the Delta CRL Indicator extension, a NULL pointer dereference may occur if the required CRL Number extension is missing. This can lead to a crash, resulting in a Denial of Service for the application. Impact summary: A NULL pointer...

Astra Linux – Vulnerability in OpenSSL

Issue summary: An invalid or NULL pointer dereference can occur in an application processing a malformed PKCS12 file. This can lead to a Denial of Service attack. Impact summary: An application processing a malformed PKCS12 file may inadvertently dereference an invalid or NULL pointer during memo...

Astra Linux – Vulnerability in OpenSSL

Issue Summary: Some non-default TLS server configurations can cause unbounded memory growth when processing TLSv1.3 sessions. Impact Summary: Attackers may exploit certain server configurations to trigger unbounded memory growth, leading to a Denial of Service attack. This issue can occur in...

Astra Linux – Vulnerability in Tomcat9

Apache Tomcat versions 8.5.0 to 8.5.63, 9.0.0-M1 to 9.0.43, and 10.0.0-M1 to 10.0.2 did not properly validate incoming TLS packets. When Tomcat was configured to use NIO+OpenSSL or NIO2+OpenSSL for TLS, a specially crafted packet could be used to trigger an infinite loop, resulting in a denial of...

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, 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

The crehash script does not properly sanitize shell metacharacters to prevent command injection. This script is distributed by some operating systems in a manner that it is automatically executed. On such operating systems, an attacker could execute arbitrary commands with the privileges of the...

Astra Linux – Vulnerability in OpenSSL

Issue summary: Calling the PKCS12getfriendlyname function on a maliciously crafted PKCS12 file with a BMPString UTF-16BE friendly name containing non-ASCII BMP code points can trigger a one-byte write before the allocated buffer. This out-of-bounds write can cause memory corruption, potentially...

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 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 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

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

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 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 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 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 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...
