A large number of share connection requests could cause a Denial of Service within Samba.
|Package||net-fs/samba on all architectures|
|Affected versions||< 3.0.22-r3|
|Unaffected versions||>= 3.0.22-r3|
Samba is a freely available SMB/CIFS implementation which allows seamless interoperability of file and print services to other SMB/CIFS clients.
During an internal audit the Samba team discovered that a flaw in the way Samba stores share connection requests could lead to a Denial of Service.
By sending a large amount of share connection requests to a vulnerable Samba server, an attacker could cause a Denial of Service due to memory consumption.
There is no known workaround at this time.
All Samba users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-fs/samba-3.0.22-r3"
