VCID-ny1w-v2d1-aaaj
Aliases: CVE-2021-23192 |
A flaw was found in the way samba implemented DCE/RPC. If a client to a Samba server sent a very large DCE/RPC request, and chose to fragment it, an attacker could replace later fragments with their own data, bypassing the signature requirements. |
Affected by 0 other vulnerabilities. |

VCID-qmfb-r5jc-aaaq
Aliases: CVE-2021-3738 |
In DCE/RPC it is possible to share the handles (cookies for resource state) between multiple connections via a mechanism called 'association groups'. These handles can reference connections to our sam.ldb database. However while the database was correctly shared, the user credentials state was only pointed at, and when one connection within that association group ended, the database would be left pointing at an invalid 'struct session_info'. The most likely outcome here is a crash, but it is possible that the use-after-free could instead allow different user state to be pointed at and this might allow more privileged access. |

VCID-sm2p-s4x5-aaae
Aliases: CVE-2020-25719 |
A flaw was found in the way Samba, as an Active Directory Domain Controller, implemented Kerberos name-based authentication. The Samba AD DC, could become confused about the user a ticket represents if it did not strictly require a Kerberos PAC and always use the SIDs found within. The result could include total domain compromise. |
Affected by 0 other vulnerabilities. |

VCID-we9h-xchf-aaam
Aliases: CVE-2020-25721 |
Kerberos acceptors need easy access to stable AD identifiers (eg objectSid). Samba as an AD DC now provides a way for Linux applications to obtain a reliable SID (and samAccountName) in issued tickets. |
