Astra Linux – Vulnerability in xwayland, xorg-server

A flaw was discovered in the handling of animated cursors by the X Rendering extension. If a client does not provide any cursors, the server assumes that at least one is present. This can lead to an out-of-bounds read and potential crash...

Astra Linux – Vulnerability in freerdp2

FreeRDP is a free implementation of the Remote Desktop Protocol RDP. Prior to version 2.7.0, server-side authentication against a SAM file might succeed with invalid credentials if the server had configured an invalid SAM file path. Clients based on FreeRDP are not affected by this issue. However...

Astra Linux – Vulnerability in Linux 6.1

Astra Linux – Vulnerability in Apache2

A timing attack against modauthdigest in Apache HTTP Server 2.4.66 allows a remote attacker to bypass Digest authentication. Users are recommended to upgrade to version 2.4.67, which fixes this issue...

Astra Linux – Vulnerability in Node.js

A memory leak occurs in Node.js HTTP/2 servers when a client sends WINDOWUPDATE frames on stream 0 connection-level that cause the flow control window to exceed the maximum value of 2³¹-1. The server correctly sends a GOAWAY frame, but the Http2Session object is never cleaned up. This vulnerabili...

Astra Linux – Vulnerability in Apache2

There is a vulnerability in the core of the Apache HTTP Server version 2.4.59 and earlier. This vulnerability allows for information disclosure, SSRF attacks, or local script execution through backend applications whose response headers are malicious or exploitable. Users are recommended to upgra...

Astra Linux – Vulnerability in xorg-server

A flaw was discovered in the X.Org server. In the XISendDeviceHierarchyEvent function, it is possible to exceed the allocated array length when certain new device IDs are added to the xXIHierarchyInfo struct. This can lead to a heap buffer overflow condition, which may result in an application...

Astra Linux – Vulnerability in Squid

A issue was discovered in Squid 4.x before 4.15, and in 5.x before 5.0.6. If a remote server sends a certain response header via HTTP or HTTPS, it can lead to a denial of service. This header can potentially appear in legitimate network traffic...

Astra Linux – Vulnerability in Apache2

HTTP/2 incoming headers that exceed the limit are temporarily buffered in nghttp2 in order to generate an informative HTTP 413 response. If a client continues to send headers, this can lead to memory exhaustion...

Astra Linux – Vulnerability in Zeromq3

A flaw was discovered in the ZeroMQ server in versions prior to 4.3.3. This flaw allows a malicious client to cause a stack buffer overflow on the server by sending crafted topic subscription requests and then unsubscribing. The greatest threat posed by this vulnerability is to confidentiality,...
