Smb4K: Multiple vulnerabilities

Smb4K: Multiple vulnerabilities Multiple vulnerabilities have been identified in Smb4K. smb4k 2007-03-09 2007-03-09 156152 local 0.6.10a 0.6.10a

Smb4K is a SMB/CIFS (Windows) share browser for KDE.

Kees Cook of the Ubuntu Security Team has identified multiple vulnerabilities in Smb4K.

The writeFile() function of smb4k/core/smb4kfileio.cpp makes insecure usage of temporary files.
The writeFile() function also stores the contents of the sudoers file with incorrect permissions, allowing for the file's contents to be world-readable.
The createLockFile() and removeLockFile() functions improperly handle lock files, possibly allowing for a race condition in file handling.
The smb4k_kill utility distributed with Smb4K allows any user in the sudoers group to kill any process on the system.
Lastly, there is the potential for multiple stack overflows when any Smb4K utility is used with the sudo command.

A local attacker could gain unauthorized access to arbitrary files via numerous attack vectors. In some cases to obtain this unauthorized access, an attacker would have to be a member of the sudoers list.

There is no known workaround at this time.

All Smb4K users should upgrade to the latest version:


    # emerge --sync
    # emerge --ask --oneshot --verbose ">=net-misc/smb4k-0.6.10a"
