Astra Linux – Vulnerability in curl

libcurl keeps previously used connections in a connection pool for subsequent transfers to reuse, if one of them matches the setup. Due to errors in the logic, the config matching function did not take ‘issuercert’ into account, and it compared the involved paths case insensitively, which could...

Astra Linux – Vulnerability in OpenSSH

OpenSSH versions prior to 10.3 omitted the confirmation of connection multiplexing for proxy-mode multiplexing sessions...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: Bluetooth: hciconn: A null pointer dereferencing occurred in hciabortconn. hciabortconn attempts to read hciskbeventhdev-sentcmd when a connection is pending. However, hdev-sentcmd can be NULL while reqstatus remains HCIREQPEN...

Astra Linux – Vulnerability in Linux

In the Linux kernel, the following vulnerabilities have been resolved: media: dvbdev: Fixed a memory leak in dvbMediaDeviceFree. The function dvbMediaDeviceFree leaks memory. It is necessary to free the dvbdev-adapter-conn object before setting it to NULL, as documented in...

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

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: MGMT: Added error handling to pairdevice. The hciconnparamsadd function never checks for a NULL value, which could lead to a NULL pointer dereferencing and resulting in a crash. This issue has been fixed by adding erro...

Astra Linux – Vulnerability in Ansible

A flaw was discovered in the ansible-connection module of Ansible Engine, where sensitive information such as Ansible user credentials is disclosed by default in the traceback error message. The greatest threat posed by this vulnerability is related to confidentiality...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: Bluetooth: hcievent: fixed a potential UAF in hcileremoteconnparamreqevt. The hciconn lookup and field access must be protected by the hdev lock in hcileremoteconnparamreqevt. Otherwise, it is possible for the lock to be...

Astra Linux – Vulnerability in bluez

BlueZ Phone Book Access Profile Heap-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of BlueZ. User interaction is required to exploit this vulnerability, as the target must connect...

Astra Linux – Vulnerability in OpenSSH

In OpenSSH versions 5.7 through 8.4, there is an observable discrepancy that can lead to an information leak during algorithm negotiations. This vulnerability allows man-in-the-middle attackers to target initial connection attempts, where no host key has been cached by the client. NOTE: Some...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: RDMA/erdma: Prevention of use-after-free in erdmaacceptnewconn After the erdmacepputnewcep function is called, newcep will be freed. The subsequent dereferencing of newcep may lead to a Use-After-Free UAF issue. This issue has be...

Astra Linux – Vulnerability in curl

A authentication bypass vulnerability exists in libcurl version 8.0.0, particularly in the connection reuse feature. This vulnerability allows for the reuse of previously established connections with incorrect user permissions, due to a failure to check for changes in the CURLOPTGSSAPIDELEGATION...

Astra Linux – Vulnerability in curl

There is an authentication bypass vulnerability in libcurl version 8.0.0, particularly in the FTP connection reuse feature. This vulnerability can cause incorrect credentials to be used during subsequent transfers. Previously created connections are retained in a connection pool for reuse if they...

Astra Linux – Vulnerability in Apache2

The Apache HTTP Server versions 2.4.6 to 2.4.46, with the modproxywstunnel module configured, were used to handle a URL. The origin server did not necessarily upgrade this connection. This setup allowed subsequent requests on the same connection to be processed without any HTTP validation,...

Astra Linux – Vulnerability in Python 2.7, Pypy

In Python 3.x versions prior to 3.5.10, 3.6.x versions prior to 3.6.12, 3.7.x versions prior to 3.7.9, and 3.8.x versions prior to 3.8.5, CRLF injection is allowed if the attacker controls the HTTP request method, as demonstrated by inserting CR and LF control characters in the first argument of...

Astra Linux – Vulnerability in curl

A authentication bypass vulnerability exists in libcurl prior to v8.0.0. It reuses an previously established SSH connection, even though one SSH option has been modified, which should prevent such reuse. libcurl maintains a pool of previously used connections and can reuse them for subsequent...
