...er@battlemech.nws.net> _____________________________________________________________________________ Summary The autofs kernel module does not check the size of the directory names it receives. It is passed the name and the names length through dentry->d_name.name and dentry->d_name.len respectively. Later on it memcpy()'s the name into a 256 byte buffer, using dentry->d_name.len as the number of bytes to copy, without checking its size. A nonprivilaged user may attempt to cd to a directory name exceeding 255 characters. This overwrites memory...
