Astra Linux – Vulnerability in Node-Elliptic

The ECDSA implementation of the Elliptic package generates incorrect signatures if the intermediate value ‘k’ calculated based on step 3.2 of RFC 6979 https://datatracker.ietf.org/doc/html/rfc6979 has leading zeros and is susceptible to cryptanalysis, which can lead to the exposure of the secret...

Astra Linux – Vulnerability in mbedtls

A vulnerability was discovered in Arm Mbed TLS before versions 2.16.6 and 2.7.x, prior to 2.7.15. An attacker who can obtain precise side-channel measurements can recover the long-term ECDSA private key by 1 reconstructing the projective coordinates of the result of scalar multiplication by...

Astra Linux – Vulnerability in Consul

The HashiCorp Consul and Consul Enterprise versions up to 1.9.4 had a key-value KV raw mode that was vulnerable to cross-site scripting attacks. This issue was fixed in versions 1.9.5, 1.8.10, and 1.7.14...

Astra Linux – Vulnerability in Linux 5.10, Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: wifi: cfg80211: Fix use after free for wext The key information in wext.connect is not reset upon reconnection, and this can retain data from a previous connection. Resetting the key data prevents drivers or mac80211 from...

Astra Linux – Vulnerability in mbedtls

The ECDSA signature implementation in ecdsa.c in Arm Mbed Crypto 2.1 and Mbed TLS from 2.19.1 onwards does not reduce the blinded scalar before computing the inverse. This allows a local attacker to recover the private key through side-channel attacks...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: libceph: Defined and enforced the CEPHMAXKEYLEN. When decoding the key, verify that the key material fits into a fixed-size buffer in processauthdone, and that its length is reasonable. The new CEPHMAXKEYLEN check replaces the...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: bpf: Fixed an out-of-bounds write in triegetnextkey The triegetnextkey function allocates a node stack with a size of trie-maxprefixlen. However, it writes trie-maxprefixlen + 1 nodes to the stack when the stack is full, after...

Astra Linux – Vulnerability in edk2

The example of an encrypted private key in EDK2, present in the IpSecDxe.efi, may pose potential security risks...

Astra Linux – Vulnerability in Samba

A flaw was discovered in Samba. The KDC accepts kpasswd requests encrypted with any key known to it. By encrypting forged kpasswd requests with its own key, a user can change other users’ passwords, allowing for full domain takeover...

Astra Linux – Vulnerability in mbedtls

A issue was discovered in Arm Mbed TLS before version 2.23.0. A side channel allows the recovery of an ECC private key, which is related to functions such as mbedtlsecpcheckpubpriv, mbedtlspkparsekey, mbedtlspkparsekeyfile, mbedtlsecpmul, and mbedtlsecpmulrestartable...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: ksmbd: The issue of a null pointer dereference error in generateencryptionkey has been fixed. If a client sends two session setups with KRB5 authentication to ksmbd, a null pointer dereference error in generateencryptionkey can...

Astra Linux – Vulnerabilities in Linux, Linux-5.15, Linux-6.1, Linux-5.10

Bluetooth BR/EDR devices with Secure Simple Pairing and Secure Connections support pairing in Bluetooth Core Specification 4.2 through 5.4. However, these devices are vulnerable to certain man-in-the-middle attacks, which force the use of a short key length. This vulnerability may lead to the...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: Input: imxsckey – fixed memory corruption upon unloading. It should be labeled as “priv”, but we accidentally passed “&priv”, which is an address in the stack. This can lead to memory corruption when the imxsckeyaction function i...

Astra Linux – Vulnerability in krb5

The file “lib/kadm5/kadmrpcxdr.c” in MIT Kerberos 5 also known as krb5 before versions 1.20.2 and 1.21.x before version 1.21.1 exposes an uninitialized pointer. A remotely authenticated user can cause a Kadmind crash. This occurs because the function xdrkadm5principalentrec does not validate the...

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 Paramiko

In Paramiko before 2.10.1, a race condition between creation and chmod in the writeprivatekeyfile function could allow unauthorized information disclosure...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: smb: client: Rejects descriptions of keys of type cifs.spnego from the user space. Keys of type cifs.spnego contain fields that carry authority information, such as pid, uid, creduid, and upcalltarget. The cifs.upcall function...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: wifi: iwlwifi: mvm: fix an issue where the TXF key sanitizer might have an off-by-one error. iwlmvmfrobtxfkeyiter tracks the last matched byte position in the loop variable ‘i’. When a full key match is found match == keylen,...

Astra Linux – Vulnerability in Redis

Redis is an in-memory database that persists data on disk. In Redis 7.0, before version 7.0.12, extracting key names from a command and a list of arguments could, in some cases, trigger a heap overflow, leading to the reading of random heap memory, heap corruption, and potentially remote code...
