Samba: Data disclosure

1. Gentoo Linux Security Advisory

Package	Vulnerable versions	Unaffected versions	Architecture(s)
net-fs/samba	< 3.0.33	>= 3.0.33	All supported architectures

Related bugreports: #247620

A missing boundary check in Samba might lead to the disclosure of memory contents.

2. Impact Information

Samba is a suite of SMB and CIFS client/server programs.

Samba does not properly check memory boundaries when handling trans, rans2, and nttrans requests.

A remote attacker could send specially crafted requests to a Samba daemon, leading to the disclosure of arbitrary memory or to a Denial of Service.

3. Resolution Information

There is no known workaround at this time.

All Samba users should upgrade to the latest version:

Code Listing 3.1: Resolution

# emerge --sync
# emerge --ask --oneshot --verbose ">=net-fs/samba-3.0.33"
