Description :

Mathieu Lafon discovered an information leak in the ext2 file system
driver. When a new directory was created, the ext2 block written to
disk was not initialized, so that previous memory contents (which
could contain sensitive data like passwords) became visible on the raw
device. This is particularly important if the target device is
removable and thus can be read by users other than root.
(CVE-2005-0400)

Yichen Xie discovered a Denial of Service vulnerability in the ELF
loader. A specially crafted ELF library or executable could cause an
attempt to free an invalid pointer, which lead to a kernel crash.
(CVE-2005-0749)

Ilja van Sprundel discovered that the bluez_sock_create() function did
not check its "protocol" argument for negative values. A local
attacker could exploit this to execute arbitrary code with root
rights by creating a Bluetooth socket with a specially crafted
protocol number. (CVE-2005-0750)

Michal Zalewski discovered that the iso9660 file system driver fails
to check ranges properly
