Freebsd : Security Vulnerabilities, CVEs, Published In 2012 (Denial of service)

The SCTP implementation in FreeBSD 8.2 allows remote attackers to cause a denial of service (NULL pointer dereference and kernel panic) via a crafted ASCONF chunk.

The Neighbor Discovery (ND) protocol implementation in the IPv6 stack in FreeBSD, NetBSD, and possibly other BSD-based operating systems allows remote attackers to cause a denial of service (CPU consumption and device hang) by sending many Router Advertisement (RA) messages with different source addresses, a similar vulnerability to CVE-2010-4670.

Multiple use-after-free vulnerabilities in libarchive 2.8.4 and 2.8.5 allow remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted (1) TAR archive or (2) ISO9660 image.

Buffer overflow in libarchive through 2.8.5 allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted TAR archive.

Multiple buffer overflows in the (1) heap_add_entry and (2) relocate_dir functions in archive_read_support_format_iso9660.c in libarchive through 2.8.5 allow remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted ISO9660 image.

Buffer overflow in libarchive 3.0 pre-release code allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted CAB file, which is not properly handled during the reading of Huffman code data within LZX compressed data.
