Descriptions

The shmctl function in Linux 2.6.9 and earlier allows local users to unlock the memory of other processes, which could cause sensitive memory to be swapped to disk, which could allow it to be read by other users once it has been released.

The Linux kernel suffers from various flaws. Michael Kerrisk noticed insufficient permission checking in the shmctl() function. OGAWA Hirofumi noticed that the table sizes in nls_ascii.c were incorrectly set to 128 instead of 256. This caused a buffer overflow in some cases which could be exploited to crash the kernel. David Coulson noticed a design flaw in the netfilter/iptables module. By sending specially crafted packets, a remote attacker could exploit this to crash the kernel or to bypass firewall rules.
