Created
05/30/2018

Description

Integer overflow in the read_nttrans_ea_list function in nttrans.c in smbd in Samba 3.x before 3.5.22, 3.6.x before 3.6.17, and 4.x before 4.0.8 allows remote attackers to cause a denial of service (memory consumption) via a malformed packet. Important Note: in order to work, the "ea support" option on the target share must be enabled.

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
