Details

Nelson Elhage discovered that Econet did not correctly handle AUN packets
over UDP. A local attacker could send specially crafted traffic to crash
the system, leading to a denial of service. (CVE-2010-4342)

Dan Rosenberg discovered that the OSS subsystem did not handle name
termination correctly. A local attacker could exploit this crash the system
or gain root privileges. (CVE-2010-4527)

Dan Rosenberg discovered that IRDA did not correctly check the size of
buffers. On non-x86 systems, a local attacker could exploit this to read
kernel heap memory, leading to a loss of privacy. (CVE-2010-4529)

Dan Carpenter discovered that the TTPCI DVB driver did not check certain
values during an ioctl. If the dvb-ttpci module was loaded, a local
attacker could exploit this to crash the system, leading to a denial of
service, or possibly gain root privileges. (CVE-2011-0521)
