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...

CVE-2026-12630: Out-of-bounds Read

Zephyr's 6LoWPAN IP Header Compression IPHC uncompression code contains an out-of-bounds read in getihpcinlinedsize subsys/net/ip/6lo.c. The destination inline size is looked up in dainlinesizetable, which has 13 entries, using an index built from the M, DAC and DAM bits of the received IPHC...

httpd: httpd: HTTP/2 Remote Denial of Service via compression bomb and Slowloris-style attack

A flaw was found in HTTP/2, affecting various web servers. A remote attacker can exploit this vulnerability by combining an HPACK compression bomb with a zero-byte flow-control window. This technique allows a small amount of data to expand into large memory allocations on the server, which are th...

The vulnerability of the ROHC analyzer in Wireshark allows a hacker to cause a service failure.

The vulnerability of the ROHC analyzer in Wireshark, which is responsible for analyzing network traffic, relates to pointer manipulation. Exploiting this vulnerability can allow attackers to cause service interruptions...

org.apache.httpcomponents.core5/httpcore5-h2: Apache HttpComponents Core: Denial of Service via oversized HTTP/2 HPACK header blocks

A flaw was found in Apache HttpComponents Core. This vulnerability, located in the HTTP/2 HPACK decoder, allows a remote attacker to cause a denial of service. By sending oversized compressed header blocks, an attacker can exhaust memory resources before the system's configured header list size...

EUVD-2026-50235

Apache Traffic Server updates the HTTP/2 HPACK dynamic table before confirming the header block encoded successfully, so an encode failure leaves the encoder out of sync with the peer decoder and corrupts subsequent header blocks on the connection. This issue affects Apache Traffic Server: from...
