Description

It was discovered that Samba did not properly perform bounds checking in certain operations. A remote attacker could possibly exploit this to read arbitrary memory contents of the smb process, which could contain sensitive infomation or possibly have other impacts, such as a denial of service.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
