Description :

David Howells discovered a local Denial of Service vulnerability in
the key session joining function. Under certain user-triggerable
conditions, a semaphore was not released properly, which caused
processes which also attempted to join a key session to hang forever.
This only affects Ubuntu 5.04 (Hoary Hedgehog). (CVE-2005-2098)

David Howells discovered a local Denial of Service vulnerability in
the keyring allocator. A local attacker could exploit this to crash
the kernel by attempting to add a specially crafted invalid keyring.
This only affects Ubuntu 5.04 (Hoary Hedgehog). (CVE-2005-2099)

Balazs Scheidler discovered a local Denial of Service vulnerability in
the xfrm_compile_policy() function. By calling setsockopt() with an
invalid xfrm_user policy message, a local attacker could cause the
kernel to write to an array beyond its boundaries, thus causing a
kernel crash. (CVE-2005-2456)

Tim Yamin discovered that the driver for compressed ISO file systems
did not sufficiently validate the iput data. By t
