The remote Debian host is missing a security-related update.
Several vulnerabilities have been discovered in the Linux kernel that may lead to a denial of service, information leaks or privilege escalation : - CVE-2014-0196 Jiri Slaby discovered a race condition in the pty layer, which could lead to denial of service or privilege escalation. - CVE-2014-1737 / CVE-2014-1738 Matthew Daley discovered that missing input sanitising in the FDRAWCMD ioctl and an information leak could result in privilege escalation. - CVE-2014-2851 Incorrect reference counting in the ping_init_sock() function allows denial of service or privilege escalation. - CVE-2014-3122 Incorrect locking of memory can result in local denial of service.
Upgrade the linux packages. For the stable distribution (wheezy), these problems have been fixed in version 3.2.57-3+deb7u1. This update also fixes a regression in the isci driver and suspend problems with certain AMD CPUs (introduced in the updated kernel from the Wheezy 7.5 point release).
