Description Erik Damrose univentionstaff 2020-09-20 21:45:31 CEST
Provide samba version 2:4.10.1-1A~4.4.0.202006301635 for UCS 4.3
First imported at bug #51532

This update addresses the following issues:
* A client combining the 'ASQ' and 'VLV' LDAP
  controls can cause a NULL pointer de-reference and
  further combinations with the LDAP paged_results
  feature can give a use-after-free in Samba's AD DC
  LDAP server. (CVE-2020-10730)
* Compression of replies to NetBIOS over TCP/IP
  name resolution and DNS packets (which can be
  supplied as UDP requests) can be abused to
  consume excessive amounts of CPU on the Samba
  AD DC (only). (CVE-2020-10745)
* The use of the paged_results or VLV controls against
  the Global Catalog LDAP server on the AD DC will cause
  a use-after-free. (CVE-2020-10760)
* The AD DC NBT server in Samba 4.0 will enter a
  CPU spin and not process further requests
  once it receives a empty (zero-length) UDP
  packet to port 137. (CVE-2020-14303)

See bug 51210 for information about a removal of the package version in UCS 4.3-5. This has to be fixed before providing the package as ES 4.3. I will remove the samba and ldb package from the ES 4.3 scope for now.
Comment 3 Ingo Steuwer univentionstaff 2021-05-14 16:49:05 CEST
should be still relevant for UCS 4.4

no, wrong bug -> still UCS 4.3
Comment 5 Erik Damrose univentionstaff 2021-06-14 09:42:10 CEST
Extended security maintenance for UCS 4.3 ended on 31 May 2021. Customers with access to 4.3 extended security maintenance did not run samba on their UCS 4.3 systems, there was no requirement to fix this in 4.3.
Bug closed.
