In the Linux kernel, the following vulnerabilities have been resolved: TCP: cdg: allows tcpcdgrelease to be called multiple times. It seems that MPTCP can call tcpdisconnect on a flow that is already disconnected. This is generally fine, unless the current congestion control mechanism is CDG, as ...

Astra Linux – Vulnerability in HAPProxy

Before version 2.7.3, HAProxy might allow a bypass of access control mechanisms, as HTTP/1 headers were inadvertently lost in certain situations, also known as “request smuggling.” The HTTP header parsers in HAProxy might accept empty header field names, which could be used to omit the list of HT...

Astra Linux – Vulnerability in Zabbix

During Zabbix installation from RPM, the DACOVERRIDE SELinux capability is used to access PID files in the /var/run/zabbix folder. In this case, processes of Zabbix Proxy or Server can bypass the file read, write, and execute permission checks at the file system level...

Astra Linux – Vulnerability in curl

When curl is used to retrieve and parse cookies from an HTTPS server, it accepts cookies using control codes that, when sent back to an HTTP server later, may cause the server to return 400 responses. This effectively allows a “sister site” to deny service to all other sibling sites...

Astra Linux – Vulnerability in libde265

There is an incorrect access control vulnerability in libde265 v1.0.8 due to a SEGV in slice.cc...

Astra Linux – Vulnerability in Keepalived

In Keepalived versions up to 2.2.4, the D-Bus mechanism does not sufficiently restrict the destination of messages, allowing any user to inspect and manipulate any property. This leads to bypasses of access controls in some situations, where a unrelated D-Bus system service has a settable writabl...
