Astra Linux – Vulnerability in Apache2

When an HTTP/2 stream is reset by a client via an RST frame, there is a time window during which the memory resources associated with the request are not immediately reclaimed. Instead, the deallocation of these resources is delayed until after the connection is closed. This allows clients to...

Astra Linux – Vulnerability in Apache2

There is a vulnerability related to HTTP response splitting in several Apache HTTP Server modules, especially on untrusted or compromised backend servers. This issue affects Apache HTTP Server versions from 2.4.66 onwards. Users are recommended to upgrade to version 2.4.67, as this version...

Astra Linux – Vulnerability in libmodbus

It was discovered that libmodbus v3.1.6 contains a use-after-free issue related to the ctx-backend pointer. This vulnerability allows attackers to trigger a Denial of Service DoS attack by sending a specially crafted message to the unit-test-server...

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 Apache2

Apache HTTP Server 2.4.53 and earlier may crash or disclose information due to a read beyond bounds in apstrcmpmatch, especially when an extremely large input buffer is used. Although no code distributed with the server can be forced to make such a call, third-party modules or Lua scripts that us...

Astra Linux – Vulnerability found in Linux 5.15, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: NFS: Fixed an error in nfsdautomount When mounting from an NFSv4 reference, path-dentry may end up being a negative dentry. Therefore, the struct nfsserver structure is derived from the dentry itself instead...

Astra Linux – Vulnerability in Pypy

In the http.cookiejar.py module of Python, prior to version 3.7.3, the domain validation mechanism was not properly implemented. This vulnerability could allow existing cookies to be sent to the wrong server. Attackers could exploit this flaw by using a server whose hostname contains another vali...

Astra Linux – Vulnerability in OpenLDAP

A flaw was discovered in OpenLDAP before version 2.4.57, which led to a crash in the slapd process during control handling of the Values Return Filter. This caused a denial of service attack, involving double-free operations and out-of-bounds reads...

Astra Linux – Vulnerability in Apache2

The out-of-bounds write vulnerability in the modsed module of the Apache HTTP Server allows an attacker to overwrite heap memory with data provided by the attacker. This issue affects Apache HTTP Server version 2.4.2.52 and earlier versions...

Astra Linux – Vulnerability in Redis

Redis before 6cbea7d allows a replica to cause an assertion failure in a primary server by sending a non-administrative command specifically, a SET command. NOTE: this issue was fixed for Redis 6.2.x and 7.x in 2021. Versions before 6.2 were not intended to have any safety guarantees related to...

Astra Linux – Vulnerability in Apache2

A regression in Apache HTTP Server 2.4.60 ignores some uses of the legacy content-type-based configuration for handlers. Configurations like “AddType” and similar settings, under certain circumstances where files are requested indirectly, can lead to exposure of local content in the source code...

Astra Linux – Vulnerability in Zeromq3

There is a flaw in the zeromq server in versions before 4.3.3, located in src/decoderallocators.hpp. The decoder’s static allocator could have its size changed, but the buffer remains unchanged since it is a static buffer. A remote, unauthenticated attacker who sends a crafted request to the zero...

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

In the Linux kernel, the following vulnerability has been resolved: net/smc: Avoid data corruption caused by decline. We identified a data corruption issue during testing of SMC-R in Redis applications. The benchmark has a low probability of reporting a strange error, as shown below: “Error:...

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

In the Linux kernel, the following vulnerability has been resolved: smb: Client: Fixed a potential Use-after-Free UAF in smb2isvalidoplockbreak. Skipped sessions that are being torn down status == SESEXITING to avoid UAF...

Astra Linux – Vulnerability in xorg-server

A vulnerability was discovered in X.Org. This security flaw arises because the handler for the ScreenSaverSetAttributes request may write to memory after it has been freed. This issue can lead to local privileges escalation on systems where the X server is running with privileged access, and may...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: smb: client: fixed potential UAF and double-free errors in smb2openfile Set @erriov and @errbuftype to zero before retrying SMB2open, to prevent UAF bugs if @data != NULL; otherwise, a double-free error will occur...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: TCP: fixed page frag corruption upon a page fault. Steffen reported a corruption of the TCP stream for HTTP requests served by the Apache web-server, using a CIFS mount-point and the corresponding file’s memory mapping. The root...
