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 – Vulnerability in Zabbix

The researcher has shown that due to the way the SNMP trap log is parsed, an attacker can create an SNMP trap with additional lines of information, causing forged data to appear in the Zabbix UI. This attack requires that SNMP authentication be disabled, and/or that the attacker knows the...

Astra Linux – Vulnerability in dovecot

Dovecot OTP authentication is vulnerable to replay attacks under certain conditions. If the auth cache is enabled, and the username is changed in passdb, then the OTP credentials can be cached, making the same OTP response valid. An attacker who can observe the OTP exchange can log in as the user...

Astra Linux – Vulnerability in Apache2

A encoding problem in the modproxy component of the Apache HTTP Server 2.4.59 and earlier versions allows request URLs with incorrect encoding to be sent to backend services, potentially bypassing authentication through crafted requests. Users are recommended to upgrade to version 2.4.60, which...

Astra Linux – Vulnerability in Firefox

The “Copy Image Link” context menu action would copy the final image URL after redirects. By embedding an image that triggered authentication flows—in conjunction with a Content Security Policy that stopped a redirection chain in the middle—the final image URL could contain an authentication toke...

Astra Linux – Vulnerability in openipmi

OpenIPMI before version 2.0.36 has a buffer overflow vulnerability related to the authentication type in the ipmisim simulator. This vulnerability can lead to denial of service, or with a very low probability authentication bypass or code execution...

Astra Linux – Vulnerability in PostgresSQL 11

When the server is configured to use trust authentication with a clientcert requirement or to use cert authentication, a man-in-the-middle attacker can inject arbitrary SQL queries during the initial establishment of a connection, despite the use of SSL certificate verification and encryption...

Astra Linux – Vulnerability in Apache2

Apache HTTP Server versions 2.4.0 to 2.4.46: A specially crafted Digest nonce can cause a stack overflow in modauthdigest. There is no report of this overflow being exploitable, nor can the Apache HTTP Server team have created such a report. However, certain compilers and/or compilation options...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: SMP – deriving legacy responder STK authentication from the MITM state The legacy responder path in smprandom currently labels the stored STK as authenticated whenever pendingseclevel is set to BTSECURITYHIGH. This...

Astra Linux – Vulnerability in dovecot

The attacker can use a specially crafted Base64 exchange between Dovecot and the client to forge SCRAM TLS channel bindings. This requires that the attacker be able to position themselves between Dovecot and the client connection. If successful, the attacker can eavesdrop on communications betwee...

Astra Linux – vulnerability in munge

MUNGE is an authentication service used to create and validate user credentials. In versions 0.5 through 0.5.17, a local attacker can exploit a buffer overflow vulnerability in munged the MUNGE authentication daemon to leak cryptographic key material from process memory. Using this leaked key...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: smb: client: fixed the issue where krb5 mounts failed when the client tried to mount shares with incorrect credentials. It turned out that the client was reusing the SMB session from the first mount attempt, even though a differe...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: SCTP: The order of operations for SCTPCMDASSOCSHKEY should be changed to right after SCTPCMDPEERINIT. A null-ptr-deref issue was reported in the SCTP transmission path when the initialization of the SCTP-AUTH key fails:...

Astra Linux – Vulnerability in exim4

Exim NTLM Challenge Out-of-Bounds Read Information Disclosure Vulnerability. This vulnerability allows remote attackers to disclose sensitive information on affected Exim installations. Authentication is not required to exploit this vulnerability. The specific flaw lies in the handling of NTLM...

Astra Linux – Vulnerability in WebKit2GTK

The issue was addressed through improved checks. This issue is fixed in Safari 17.5, iOS 16.7.8 and iPadOS 16.7.8, iOS 17.5 and iPadOS 17.5, macOS Sonoma 14.5, tvOS 17.5, and watchOS 10.5. An attacker with arbitrary read and write capabilities may be able to bypass Pointer Authentication...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: libceph: The handler error from monhandleauthdone should be returned. Currently, any error from cephauthhandlereplydone is propagated via finishauth, but it is not returned from monhandleauthdone. This results in higher layers...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: Staging: rtl8723bs: Fixed issues with WEP length underflow and OOB read during the OnAuth process. OnAuth contains two bugs in the shared-key authentication process. When the Privacy bit is set, rtwwepdecrypt is called without...

Astra Linux – Vulnerability in imagemagick

ImageMagick is free and open-source software used for editing and manipulating digital images. Before versions 6.9.13-48 and 7.1.2-23, the distributed pixel cache was originally designed to work without a challenge-response authentication model. This has been changed in versions 6.9.13-48 and...

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.
