In Apache HTTP Server versions 2.4.0 to 2.4.46, a specially crafted SessionHeader sent by an origin server could cause a heap overflow...

Astra Linux – Vulnerability in nghttp2

nghttp2 is an implementation of the Hypertext Transfer Protocol Version 2 in C. The nghttp2 library prior to version 1.61.0 continued to read an unlimited number of HTTP/2 CONTINUATION frames even after a stream was reset, in order to keep the HPACK context synchronized. This caused excessive CPU...

Astra Linux – Vulnerability in Linux

The 802.11 standard that underpins Wi-Fi Protected Access WPA, WPA2, and WPA3 and Wired Equivalent Privacy WEP does not require that the A-MSDU flag in the plaintext QoS header field be authenticated. Against devices that support receiving non-SSP A-MSDU frames which is mandatory as part of...

Astra Linux – Vulnerability in Firefox

By using iterative requests, an attacker was able to determine the size of an opaque response, as well as the contents of a Vary header provided by the server. This vulnerability affects Firefox versions earlier than 119...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: x86/fpu: State corruption has been prevented in fpurestoresig. The non-compacted slowpath uses copyfromuser to copy the entire user buffer into the kernel buffer, verbatim. This means that the kernel buffer may now contain entire...

Astra Linux – Vulnerability in Tomcat9

A denial-of-service attack occurs due to a vulnerability related to improper input validation in HTTP/2 requests handled by Apache Tomcat. When processing an HTTP/2 request, if the request exceeds any of the configured header limits, the associated HTTP/2 stream is not reset until all headers hav...

Astra Linux – Vulnerability in Golang-1.19

The HTTP/1 client does not fully validate the contents of the Host header. A maliciously crafted Host header can inject additional headers or entire requests. With this fix, the HTTP/1 client will now refuse to send requests that contain an invalid Request.Host or Request.URL.Host value...

Astra Linux – Vulnerability in librabbitmq

A issue was discovered in amqphandleinput within amqpconnection.c in rabbitmq-c 0.9.0. There is an integer overflow that leads to heap memory corruption during the handling of THE CONNECTIONSTATEHEADER. A malicious server could return a malicious frame header, resulting in a smaller targetsize...

Astra Linux – Vulnerability in Firefox and Thunderbird

Firefox incorrectly accepted a new line in an HTTP/3 header, interpreting it as two separate headers. This allowed for a header splitting attack against servers using HTTP/3. This vulnerability affects Firefox 91.0.1 and Thunderbird 91.0.1...
