Integer overflow in the inet_net_pton API in Libsystem in Apple Mac OS X before 10.5.6 allows context-dependent attackers to execute arbitrary code or cause a denial of service (application crash) via unspecified vectors. NOTE: this may be related to the WLB-2008080064 advisory published by SecurityReason on 20080822; however, as of 20081216, there are insufficient details to be sure.

The kernel in Apple Mac OS X before 10.5.6 allows local users to cause a denial of service (infinite loop and system halt) by running an application that is dynamically linked to libraries on an NFS server, related to occurrence of an exception in this application.

Multiple integer overflows in the kernel in Apple Mac OS X before 10.5.6 on Intel platforms allow local users to gain privileges via a crafted call to (1) i386_set_ldt or (2) i386_get_ldt.

Integer signedness error in BOM in Apple Mac OS X before 10.5.6 allows remote attackers to execute arbitrary code via the headers in a crafted CPIO archive, leading to a stack-based buffer overflow.

The plug-in interface in WebKit in Apple Safari before 3.2 does not prevent plug-ins from accessing local URLs, which allows remote attackers to obtain sensitive information via vectors that “launch local files.”

Weblog in Mac OS X Server 10.4.11 does not properly check an error condition when a weblog posting access control list is specified for a user that has multiple short names, which might allow attackers to bypass intended access restrictions.
