Title: Linux kernel vulnerabilities
Summary: Linux kernel vulnerabilities
It was discovered that the direct-IO subsystem did not correctly validate
certain structures. A local attacker could exploit this to cause a system
crash, leading to a denial of service. (CVE-2007-6716)
It was discovered that the disabling of the ZERO_PAGE optimization could
lead to large memory consumption. A local attacker could exploit this to
allocate all available memory, leading to a denial of service.
(CVE-2008-2372)
It was discovered that the Datagram Congestion Control Protocol (DCCP) did
not correctly validate its arguments. If DCCP was in use, a remote attacker
could send specially crafted network traffic and cause a system crash,
leading to a denial of service. (CVE-2008-3276)
