Description:
Stefan Esser has reported a vulnerability in Samba, which can be exploited by malicious users to compromise a vulnerable system.
The vulnerability is caused due to a boundary error in the QFILEPATHINFO request handler when constructing "TRANSACT2_QFILEPATHINFO" responses and can be exploited to cause a buffer overflow.
Successful exploitation allows execution of arbitrary code, but requires that a special pathname exists or that the user has write permissions on a network share.
The vulnerability has been reported in version 3.0.7 and prior.
Solution:
Update to version 3.0.8.
