Multiple vulnerabilities have been identified in Smb4K.
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
- 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
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:
