linux linux kernel 2.6.20.18 vulnerabilities and exploits

(subscribe to this query)

The bdx_ioctl_priv function in the tehuti driver (tehuti.c) in Linux kernel 2.6.x prior to 2.6.25.1 does not properly check certain information related to register size, which has unspecified impact and local attack vectors, probably related to reading or writing kernel memory.

Buffer overflow in fs/cifs/connect.c in CIFS in the Linux kernel 2.6.29 and previous versions allows remote malicious users to cause a denial of service (crash) via a long nativeFileSystem field in a Tree Connect response to an SMB mount request.

The (1) agp_generic_alloc_page and (2) agp_generic_alloc_pages functions in drivers/char/agp/generic.c in the agp subsystem in the Linux kernel prior to 2.6.30-rc3 do not zero out pages that may later be available to a user-space process, which allows local users to obtain sensit...

The swiotlb functionality in the r8169 driver in drivers/net/r8169.c in the Linux kernel prior to 2.6.27.22 allows remote malicious users to cause a denial of service (IOMMU space exhaustion and system crash) by using jumbo frames for a large amount of network traffic, as demonst...

1 EDB exploit

The __inet6_check_established function in net/ipv6/inet6_hashtables.c in the Linux kernel prior to 2.6.29, when Network Namespace Support (aka NET_NS) is enabled, allows remote malicious users to cause a denial of service (NULL pointer dereference and system crash) via vectors in...

Buffer overflow in the lbs_process_bss function in drivers/net/wireless/libertas/scan.c in the libertas subsystem in the Linux kernel prior to 2.6.27.5 allows remote malicious users to have an unknown impact via an "invalid beacon/probe response."

The sock_getsockopt function in net/core/sock.c in the Linux kernel prior to 2.6.28.6 does not initialize a certain structure member, which allows local users to obtain potentially sensitive information from kernel memory via an SO_BSDCOMPAT getsockopt request.

1 EDB exploit

The ip6_dst_lookup_tail function in net/ipv6/ip6_output.c in the Linux kernel prior to 2.6.27 does not properly handle certain circumstances involving an IPv6 TUN network interface and a large number of neighbors, which allows malicious users to cause a denial of service (NULL po...

1 EDB exploit

Stack-based buffer overflow in the parse_tag_11_packet function in fs/ecryptfs/keystore.c in the eCryptfs subsystem in the Linux kernel prior to 2.6.30.4 allows local users to cause a denial of service (system crash) or possibly gain privileges via vectors involving a crafted eCr...
