Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: sctp: Handle the error returned from sctpauthasocinitactivekey. When an error is returned from sctpauthasocinitactivekey, the activekey is not actually updated. The old shkey remains freed while it’s still being used as the activ...

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 squid

Squid is vulnerable to a Denial of Service attack; a remote attacker can perform a buffer overflow attack by writing up to 2 MB of arbitrary data to heap memory when Squid is configured to accept HTTP Digest Authentication...

Astra Linux – vulnerability in curl

A authentication bypass vulnerability exists in libcurl prior to v8.0.0; it reuses an SSH connection that has already been established, even though an SSH option was modified—which should have prevented such reuse. libcurl maintains a pool of previously used connections and reuses them for...

Astra Linux – Vulnerability in Tomcat9

Authentication Bypass Using an Alternate Path or Channel vulnerability in Apache Tomcat. When using PreResources or PostResources mounted elsewhere beyond the root of the web application, it was possible to access those resources via an unexpected path. That path was likely not protected by the...

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 Chromium

After free in WebAuthentication in Google Chrome prior to 149.0.7827.53 allowed a remote attacker who convinced a user to engage in specific UI gestures to potentially exploit heap corruption via a crafted HTML page. Chromium security severity: High...

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 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 Tomcat9

A critical step is missing in the authentication process of Apache Tomcat; when the JNDIRealm was configured to authenticate binds via GSSAPI, attackers could authenticate without providing the correct password. This issue affects Apache Tomcat versions 11.0.0-M1 through 11.0.4, 10.1.0-M1 through...

Astra Linux – vulnerability in cyrus-sasl2

In Cyrus SASL versions 2.1.17 through 2.1.27 up to and including 2.1.28, the plugin/sql.c file fails to escape the password used in SQL INSERT or UPDATE statements...

Astra Linux – vulnerability in linux-5.15

An issue was found in net/ceph/messengerv2.c within the Linux kernel prior to version 6.4.5. There is an integer signedness error that results in a buffer overflow, enabling remote code execution via the HELLO message or one of the AUTH frames. This occurs due to an untrusted length value extract...

Astra Linux – Vulnerability in Tomcat9

DEPRECATED: There is a vulnerability related to authentication bypass in digest authentication in Apache Tomcat. This issue affects Apache Tomcat versions as follows: 11.0.0-M1 through 11.0.21, 10.1.0-M1 through 10.1.54, 9.0.0.M1 through 9.0.117, 8.5.0 through 8.5.100, and versions prior to 7.0.0...

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 – Vulnerabilities in Linux 5.10, Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: SCTP: The comparison of MACs has been fixed to require constant-time operations. To prevent timing attacks, MACs need to be compared in constant-time. Use the appropriate helper function for this purpose...

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 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 freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.26.0, FreeRDP’s RDPEAR NDR parser accepted one non-null NDR pointer ref-id for multiple logical pointer fields, without tracking the expected NDR type or ownership of the pointed object. When the same ref-id was...

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...
