Astra Linux – Vulnerability in krb5

The vulnerability of the uccanoncompatdecomp function in the ucdata.c component of the Kerberos authentication protocol is related to a buffer overflow in the stack. Exploiting this vulnerability allows an attacker to access confidential data, compromise its integrity, and cause service failures...

Astra Linux – Vulnerability in Samba

A flaw was identified in the way Samba, as an Active Directory Domain Controller, implemented Kerberos name-based authentication. If Samba’s AD DC did not strictly require a Kerberos PAC and always used the SIDs contained within it, it could become confused about the user represented by a ticket...

Astra Linux – Vulnerability in Samba, Heimdal

A null pointer de-reference was detected in the way the Samba Kerberos server handled the absence of the sname in the TGS-REQ Ticket Granting Server – Request. A authenticated user could exploit this flaw to crash the Samba server...

Astra Linux – Vulnerability in krb5

The vulnerability of the getmechset function in the spnegomech.c component of the Kerberos authentication protocol is related to reading data from within a permissible buffer size. Exploiting this vulnerability allows an attacker to cause service failures...

Astra Linux – Vulnerability in freeipa

A vulnerability was discovered in FreeIPA regarding the initial implementation of MS-SFU by MIT Kerberos. This implementation lacked a condition for granting the “forwardable” flag on S4U2Self tickets. Fixing this issue required adding a special case for the checkallowedtodelegate function: If th...

Astra Linux – Vulnerability in krb5

The Key Distribution Center KDC in MIT Kerberos 5 also known as krb5 before version 1.18.5 and 1.19.x before version 1.19.3 has a NULL pointer dereference in the kdc/dotgsreq.c file, due to a FAST inner body that lacks a server field...

Astra Linux – Vulnerability in sssd

A flaw was discovered in the integration of Active Directory and the System Security Services Daemon SSSD on Linux systems. In default configurations, the Kerberos local authentication plugin sssdkrb5localauthplugin is enabled, but a fallback to the an2ln plugin is possible. This fallback allows ...

Astra Linux – Vulnerability in Heimdal

All Samba versions 4.x.x before 4.9.17, 4.10.x before 4.10.11, and 4.11.x before 4.11.3 have a issue where the S4U MS-SFU Kerberos delegation model includes a feature that allows a subset of clients to be opt-out from constrained delegation in either S4U2Self or regular Kerberos authentication...

Astra Linux – Vulnerability in krb5

The vulnerability of the decodekrb5flags function in the asn1kencode.c component of the Kerberos authentication protocol is related to integer overflow. Exploiting this vulnerability allows a malicious actor to cause a service denial...

Astra Linux – Vulnerability in krb5

The vulnerability of the krb5chpwmessage function in the Kerberos authentication protocol is related to insufficient input validation. Exploiting this vulnerability allows an attacker to access confidential data and also cause service interruptions...

Astra Linux – Vulnerability in Heimdal, KRB5

PAC parsing in MIT Kerberos 5 also known as krb5 before versions 1.19.4 and 1.20.x before version 1.20.1 contains integer overflows that may lead to remote code execution in the KDC, kadmind, or a GSS or Kerberos application server on 32-bit platforms. This results in a heap-based buffer overflow...

Astra Linux – Vulnerability in krb5

In MIT Kerberos 5 also known as krb5, before version 1.21.3, an attacker could modify the plaintext Extra Count field of a confidential GSS krb5 wrap token. This modification caused the unwrapped token to appear truncated, affecting the application...

Astra Linux – Vulnerability in freeipa

A privilege escalation from the host to the domain vulnerability was identified in the FreeIPA project. By default, the FreeIPA package fails to validate the uniqueness of the krbCanonicalName for the admin account, allowing users to create services with the same canonical name as the REALM admin...

Astra Linux – Vulnerability in Samba

A flaw was discovered in the way Samba implemented SMB1 authentication. An attacker could exploit this flaw to retrieve the plain-text password sent over the network, even if Kerberos authentication was required...

Astra Linux – Vulnerability in krb5

The RADIUS protocol, as described in RFC 2865, is vulnerable to forgery attacks by local attackers who can modify any valid response—whether an Access-Accept, Access-Reject, or Access-Challenge response—into any other response, using a chosen-prefix collision attack against the MD5 Response...

Astra Linux – Vulnerability in Samba

Kerberos acceptors need easy access to stable AD identifiers e.g., objectSid. Samba, as an AD DC, now provides a way for Linux applications to obtain a reliable SID and samAccountName from the issued tickets...

Astra Linux – Vulnerability in curl

When curl 7.84.0 performs FTP transfers secured by krb5, it incorrectly handles message verification failures. This flaw allows a Man-In-The-Middle attack to go unnoticed, and even enables the attacker to inject data into the client’s system...
