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 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 found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: crypto: virtio – Add spinlock protection with virtqueue notification When a virtual machine boots with a virtio-crypto PCI device and a built-in backend, run the openssl benchmark command with multiple processes. For example:...

Astra Linux – Vulnerability in OpenSSL

Issue summary: There is a type confusion vulnerability in the signature verification of signed PKCS7 data. In this vulnerability, an ASN1TYPE union member is accessed without first validating the type, resulting in an invalid or NULL pointer dereferencing during the processing of malformed PKCS7...

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 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

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 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 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 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

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 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: 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

Issue Summary: Checking excessively long DH keys or parameters can be very slow. Impact Summary: Applications that use functions like DHcheck, DHcheckex, or EVPPKEYparamcheck to check DH keys or parameters may experience prolonged delays. If the keys or parameters are obtained from an untrusted...

Astra Linux – Vulnerability in OpenSSL

Issue summary: Processing a maliciously formatted PKCS12 file may cause OpenSSL to crash, leading to a potential Denial of Service attack. Impact summary: Applications that load files in PKCS12 format from untrusted sources may experience abrupt termination. A PKCS12 format file can contain...

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

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

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...
