smb4k 0.4 and other versions before 0.6.3 allows local users to read sensitive files via a symlink attack on the (1) smb4k.tmp or (2) sudoers temporary files.

Multiple race conditions in Smb4K before 0.8.0 allow local users to (1) modify arbitrary files via unspecified manipulations of Smb4K's lock file, which is not properly handled by the remove_lock_file function in core/smb4kfileio.cpp, and (2) add lines to the sudoers file via a symlink attack on temporary files, which isn't properly handled by the writeFile function in core/smb4kfileio.cpp.

The writeFile function in core/smb4kfileio.cpp in Smb4K before 0.8.0 does not preserve /etc/sudoers permissions across modifications, which allows local users to obtain sensitive information (/etc/sudoers contents) by reading this file.

Smb4K before 0.8.0 allow local users, when present on the Smb4K sudoers list, to kill arbitrary processes, related to a "design issue with smb4k_kill."

Multiple stack-based buffer overflows in utilities/smb4k_*.cpp in Smb4K before 0.8.0 allow local users, when present on the Smb4K sudoers list, to gain privileges via unspecified vectors related to the args variable and unspecified other variables, in conjunction with the sudo configuration.
