Description:
iDEFENSE has reported a vulnerability in Samba, which can be exploited by malicious users to compromise a vulnerable system.
The vulnerability is caused due to an integer overflow within smbd when handling security descriptors. This can be exploited to cause a heap-based buffer overflow by requesting an extremely large amount of security descriptors.
Successful exploitation allows execution of arbitrary code, but requires that the user has proper credentials to access a share.
The vulnerability affects versions 2.x and 3.0.x up to and including version 3.0.9.
Solution:
Apply patch for Samba 3.0.9:
http://us1.samba.org/samba/ftp/patches/security/samba-3.0.9-CAN-2004-1154.patch
Provided and/or discovered by:
Greg MacManus, iDEFENSE Labs.
Changelog:
