kernel: l2tp: Fix oops in pppol2tp_xmit

The pppol2tp_xmit function in drivers/net/pppol2tp.c in the L2TP implementation in the Linux kernel before 2.6.34 does not properly validate certain values associated with an interface, which allows attackers to cause a denial of service (NULL pointer dereference and OOPS) or possibly have unspecified other impact via vectors related to a routing change.

libtiff: OJPEGReadBufferFill NULL deref crash

LibTIFF 3.9.4 and earlier does not properly handle an invalid td_stripbytecount field, which allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted TIFF file, a different vulnerability than CVE-2010-2443.

libtiff: OJPEGReadBufferFill NULL deref crash

The OJPEGReadBufferFill function in tif_ojpeg.c in LibTIFF before 3.9.3 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via an OJPEG image with undefined strip offsets, related to the TIFFVGetField function.

wireshark: SMB PIPE dissector NULL pointer dereference

The SMB PIPE dissector in Wireshark 0.8.20 through 1.0.13 and 1.2.0 through 1.2.8 allows remote attackers to cause a denial of service (NULL pointer dereference) via unknown vectors.

krb5: null pointer dereference in GSS-API library leads to DoS (MITKRB5-SA-2010-005)

The kg_accept_krb5 function in krb5/accept_sec_context.c in the GSS-API library in MIT Kerberos 5 (aka krb5) through 1.7.1 and 1.8 before 1.8.2, as used in kadmind and other applications, does not properly check for invalid GSS-API tokens, which allows remote authenticated users to cause a denial of service (NULL pointer dereference and daemon crash) via an AP-REQ message in which the authenticator's checksum field is missing.

kernel: ipv6: fix ip6_dst_lookup_tail() NULL pointer dereference

The ip6_dst_lookup_tail function in net/ipv6/ip6_output.c in the Linux kernel before 2.6.27 does not properly handle certain circumstances involving an IPv6 TUN network interface and a large number of neighbors, which allows attackers to cause a denial of service (NULL pointer dereference and OOPS) or possibly have unspecified other impact via unknown vectors.

kvm: vmx null pointer dereference

The Hypervisor (aka rhev-hypervisor) in Red Hat Enterprise Virtualization (RHEV) 2.2, and KVM 83, when the Intel VT-x extension is enabled, allows guest OS users to cause a denial of service (NULL pointer dereference and host OS crash) via vectors related to instruction emulation.

php: NULL pointer dereference in XML-RPC extension

The xmlrpc extension in PHP 5.3.1 does not properly handle a missing methodName element in the first argument to the xmlrpc_decode_request function, which allows context-dependent attackers to cause a denial of service (NULL pointer dereference and application crash) and possibly have unspecified other impact via a crafted argument.

mod_auth_openidc core dump when OIDCStripCookies is set and an empty Cookie header is supplied

mod_auth_openidc is an authentication and authorization module for the Apache 2.x HTTP server that implements the OpenID Connect Relying Party functionality. In versions 2.0.0 through 2.4.13.1, when `OIDCStripCookies` is set and a crafted cookie supplied, a NULL pointer dereference would occur, resulting in a segmentation fault. This could be used in a Denial-of-Service attack and thus presents an availability risk. Version 2.4.13.2 contains a patch for this issue. As a workaround, avoid using `OIDCStripCookies`.

NVIDIA GPU Display Driver for Windows and Linux contains a vulnerability in the kernel mode layer, where an unprivileged user can cause a null-pointer dereference, which may lead to denial of service.

GPAC MP4box 2.1-DEV-rev574-g9d5bb184b is vulnerable to Null pointer dereference via filters/dmx_m2ts.c:343 in m2tsdmx_declare_pid

Null pointer dereference in Bluetooth HOST

Transient DOS due to null pointer dereference in Bluetooth HOST while receiving an attribute protocol PDU with zero length data.

Null pointer dereference in Bluetooth HOST

Transient DOS in Bluetooth HOST due to null pointer dereference when a mismatched argument is passed.

Null pointer dereference in Linksys WRT54GL

A null pointer dereference vulnerability exists in Linksys WRT54GL Wireless-G Broadband Router with firmware <= 4.30.18.006. A null pointer dereference in the soap_action function within the upnp binary can be triggered by an unauthenticated attacker via a malicious POST request invoking the AddPortMapping action.

firefox: thunderbird: Null Pointer Dereference in PKCS#12 Utility

A null pointer dereference may have inadvertently occurred in `pk12util`, and specifically in the `SEC_ASN1DecodeItem_Util` function, when handling malformed or improperly formatted input files. This vulnerability affects Firefox < 133 and Thunderbird < 133.

kernel: null-ptr-deref vulnerabilities in sl_tx_timeout in drivers/net/slip

A flaw was found in the Linux kernel. A NULL pointer dereference may occur while a slip driver is in progress to detach in sl_tx_timeout in drivers/net/slip/slip.c. This issue could allow an attacker to crash the system or leak internal kernel information.
