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 gnutls28

A vulnerability was identified: the response times for malformed ciphertexts in RSA-PSK ClientKeyExchange differ from those of ciphertexts with correct PKCS1 v1.5 padding...

Astra Linux – Vulnerability in nss, Thunderbird

Versions of NSS Network Security Services prior to 3.73 or 3.68.1 ESR are vulnerable to a heap overflow when handling DER-encoded DSA or RSA-PSS signatures. Applications that use NSS to handle signatures encoded within CMS, S/MIME, PKCS \7, or PKCS \12 are likely to be affected. Applications that...

Astra Linux – Vulnerability in nss

During RSA key generation, bignum implementations used a variant of the Binary Extended Euclidean Algorithm, which involved significant input-dependent processes. This allowed attackers to perform electromagnetic-based side-channel attacks to capture traces that could lead to the recovery of secr...

Astra Linux – Vulnerability in mbedtls

A vulnerability was discovered in Mbed TLS before versions 2.28.2 and 3.x, prior to 3.3.0. An adversary with access to sufficiently precise information about memory accesses typically, an untrusted operating system attacking a secure environment can retrieve an RSA private key by observing the...

Astra Linux – Vulnerability in openssl1.0

There is an overflow bug in the x6464 Montgomery squaring procedure used in exponentiation with 512-bit moduli. No EC algorithms are affected. Analysis suggests that attacks against 2-prime RSA1024, 3-prime RSA1536, and DSA1024 as a result of this defect would be very difficult to perform and are...

Astra Linux – Vulnerability in python-cryptography

Python-Cryptography 3.2 is vulnerable to Bleichenbacher timing attacks in the RSA decryption API, due to timed processing of valid PKCS1 v1.5 ciphertext...

Astra Linux – Vulnerability in mbedtls

The use of a broken or risky cryptographic algorithm in the function mbedtlsmpiexpmod in lignum.c in Mbed TLS for all versions prior to 3.0.0, 2.27.0, or 2.16.11 allows attackers with access to precise timing and memory access information typically from an untrusted operating system attacking a...

Astra Linux – Vulnerability in gnupg1

Libgcrypt before version 1.7.8 is vulnerable to a cache-side-channel attack that can lead to a complete failure of the RSA-1024 algorithm. This attack occurs when the left-to-right method is used for computing the sliding-window expansion. It is believed that the same attack also works on the...

Astra Linux – Vulnerability in Thunderbird

Thunderbird versions prior to 91.3.0 are vulnerable to a heap overflow vulnerability described in CVE-2021-43527 when processing S/MIME messages. Thunderbird versions 91.3.0 and later will not call the vulnerable code when processing S/MIME messages that contain certificates with DER-encoded DSA ...

Astra Linux – Vulnerability in Thunderbird, Firefox

When importing an SPKI RSA public key as an ECDSA P-256 key, the key is handled incorrectly, causing the tab to crash. This vulnerability affects Firefox 110, Thunderbird 102.8, and Firefox ESR 102.8...

Astra Linux – Vulnerability in gnutls28

A vulnerability was discovered in GnuTLS. The response times to malformed ciphertexts in the RSA-PSK ClientKeyExchange differ from those of ciphertexts with correct PKCS1 v1.5 padding. This issue may allow a remote attacker to perform a timing side-channel attack during the RSA-PSK key exchange,...

openssl: OpenSSL: Denial of Service due to NULL pointer dereference in CMS EnvelopedData processing

A flaw was found in OpenSSL. A remote attacker could exploit this vulnerability by sending a specially crafted Cryptographic Message Syntax CMS EnvelopedData message. During the processing of a KeyTransportRecipientInfo with RSA-OAEP encryption, the system attempts to access an optional parameter...

PT-2026-80926

The use of hard-coded cryptographic key vulnerability has been identified in the mesh functionality of Deco XE75 v3, XE5300 v3.6 and WE10800 v3.6. A shared RSA-512 mesh group private key is present in the affected firmware and is used by the mesh protocol for node authentication. An attacker who...

CVE-2026-62381 luci-lib-px5g 2040-bit Certificate Signing Heap Buffer Overflow

luci-lib-px5g LuCI contains a heap-based buffer overflow in the native ASN.1 encoding routine asn1addobj x509write.c when signing a certificate with a 2040-bit RSA key. For a 255-byte signature, the BIT STRING allocation is computed from the DER length encoding of 255 bytes, but the payload writt...

CVE-2026-62381

luci-lib-px5g (LuCI) in OpenWrt contains a heap-based buffer overflow in the ASN.1 encoding routine asn1_add_obj (x509write.c) triggered when signing a certificate with a 2040-bit RSA key . The BIT STRING allocation is sized for a 255-byte signature's DER length encoding, but prepending the unuse...

librenswan: IKEv2 Denial of Service via RSA-SHA1 (PKCS#1 RSASSA-PKCS1-v1_5) authentication payload

A flaw was found in Libreswan's implementation of IKEv2 authentication when processing signatures utilizing the RSASSA-PKCS1-v15 scheme. The RSAauthenticatehashsignaturepkcs115rsa function does not correctly validate the DER encoding of the ASN.1 digest. A remote, unauthenticated attacker could...

librenswan: IKEv1 Denial of Service via RSA-SHA1 (PKCS#1 Version 1.5 Encrypted) authentication payload

A flaw was found in Libreswan's implementation of IKEv1 authentication via raw RSA signatures. When processing an IKEv1 packet using PKCS 1 v1.5 RSA encryption, the RSAauthenticatehashsignaturerawrsa function fails to properly validate the length of the authentication hash. A remote,...

EUVD-2026-62948

In versions below 1.0.5 of the RSA SecurID Authentication Manager app for Splunk SOAR, a user who holds a role with permission to run actions could expose a sensitive token serial by invoking either the enable token or revoke token action, because the action's tokenserial parameter is not masked...
