kernel: rxrpc: Fix timeout of a call that hasn't yet been granted a channel

A NULL pointer dereference flaw was found in the Linux kernel's RxRPC/AFS networking stack. When making an AFS call, the call timer can expire before a connection is assigned if the call gets stalled waiting for a connection. This causes a NULL pointer dereference in rxrpcalloctxbuf when attempti...

Samba服务器VFS插件afsacl.so远程格式串处理漏洞

Samba是一套实现SMB（Server Messages Block）协议、跨平台进行文件共享和打印共享服务的程序。 Samba的VFS插件afsacl.so库在处理文件名时存在格式串漏洞，攻击者可能利用此漏洞诱使用户处理恶意的VFS分区控制服务器。 Samba在调用snprintf时将磁盘上所储存的文件名用作了格式串，如果用户能够写入的共享使用Samba的afsacl.so库对AFS文件系统上的文件设置Windows NT访问控制列表的话，就可能通过文件名中的格式串标识符导致执行任意代码。 这个漏洞仅影响与CIFS共享了AFS文件系统并在smb.conf中明确要求加载afsacl.s...
