Vulnerability Assessment Details

USN29-1 : samba vulnerability

Vulnerability Assessment Summary
samba vulnerability

Detailed Explanation for this Vulnerability Assessment

Summary :

These remote packages are missing security patches :
- libpam-smbpass
- libsmbclient
- libsmbclient-dev
- python2.3-samba
- samba
- samba-common
- samba-doc
- smbclient
- smbfs
- swat
- winbind


Description :

During an audit of the Samba 3.x code base Stefan Esser discovered a
Unicode file name buffer overflow within the handling of
TRANSACT2_QFILEPATHINFO replies. A malicious samba user with write
access to a share could exploit this by creating specially crafted
path names (files with very long names containing Unicode characters)
that would overflow an internal buffer and could lead to remote
execution of arbitrary code with the rights of the samba server.

Since the samba server usually (by default) runs as root, this flaw
can lead to privilege escalation and unbounded system compromise.

Solution :

Upgrade to :
- libpam-smbpass-3.0.7-1ubuntu6.2 (Ubuntu 4.10)
- libsmbclient-3.0.7-1ubuntu6.2 (Ubuntu 4.10)
- libsmbclient-dev-3.0.7-1ubuntu6.2 (Ubuntu 4.10)
- python2.3-samba-3.0.7-1ubuntu6.2 (Ubuntu 4.10)
- samba-3.0.7-1ubuntu6.2 (Ubuntu 4.10)
- samba-common-3.0.7-1ubuntu6.2 (Ubuntu 4.10)
- samba-doc-3.0.7-1ubuntu6.2 (Ubuntu 4.10)
- smbclient-3.0.7-1ubuntu6.2 (Ubuntu 4.10)
- smbfs-3.0.7-1ubuntu6.2 (Ubuntu 4.10)
- swat-3.0.7-1ubuntu6.2 (Ubuntu 4.10)
- winbind-3.0.7-1ubuntu6.2 (Ubuntu 4.10)
