Leak in Samba Versions from 3.0.29
Samba versions from 3.0.29 include a security failure. Developers have released an update to fix it.
The Samba advisory indicates that the security leak resulted from a change to GNU Compiler Collection (GCC) version 4 optimization. It seems a cut-and-paste error in the range checking code can allow a malicious client to alter the Server Message Block (SMB) process to pass arbitrary memory requests back to itself.
The Samba team ran into the error during an internal code investigation. The advisory recommends an immediate patch upgrade.
Patches are available for download here. The new Samba versions, 3.2.5 and 3.0.33 already have the patches applied. The team also points to the fact that the Samba 3.2 directories are now located in the /recent directory and are no longer in an experimental state.
