An old inffast.c optimization turns out to not be optimal anymore with modern compilers, and furthermore was not compliant with the C standard, for which decrementing a pointer before its allocated memory is undefined.

Heap-based buffer overflow in the DHCP client (udhcpc) in BusyBox before 1.25.0 allows remote attackers to have unspecified impact via vectors involving OPTION6RD parsing.

An upgrade to zlib 1.2.11 to fix a number of low severity CVEs that were present in zlib 1.2.8.

Undisclosed traffic can cause the Traffic Management Microkernel (TMM) to terminate.  This issue may occur when a Datagram Transport Layer Security (DTLS) 1.2 virtual server is enabled with a Server SSL profile that is configured with a certificate, key, and the SSL Sign Hash set to ANY, and the backend server is enabled with DTLS 1.2 and client authentication.  Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.

When a client SSL profile is configured on a virtual server, undisclosed requests can cause an increase in memory resource utilization.

When a virtual server, network address translation (NAT) object, or secure network address translation (SNAT) object uses the embedded Packet Velocity Acceleration (ePVA) feature, and the Auto Last Hop setting is disabled, undisclosed traffic can cause the Traffic Management Microkernel (TMM) to terminate. The Auto Last Hop setting is enabled globally by default. For more information about the Auto Last Hop setting, refer to K13876: Overview of the Auto Last Hop setting (15.x - 17.x). To determine which BIG-IP platforms have an ePVA chip, refer to K12837: Overview of the ePVA feature.

When using a multi-bladed platform with more than one active blade, undisclosed traffic can cause the Traffic Management Microkernel (TMM) to terminate.

When IPsec is configured on the BIG-IP system, undisclosed traffic can cause the Traffic Management Microkernel (TMM) to terminate.

When running in Appliance mode, a highly privileged authenticated attacker with access to SCP and SFTP may be able to bypass Appliance mode restrictions using undisclosed commands.  Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.

A vulnerability exists in an undisclosed iControl REST and BIG-IP TMOS Shell (tmsh) command that may allow an authenticated attacker with at least resource administrator role to execute arbitrary system commands with higher privileges.  A successful exploit can allow the attacker to cross a security boundary.  Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.

A validation vulnerability exists in an undisclosed URL in the Configuration utility.  Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.

A vulnerability exists in the iHealth command that may allow an authenticated attacker with at least a resource administrator role to bypass tmsh restrictions and gain access to a bash shell.  For BIG-IP systems running in Appliance mode, a successful exploit can allow the attacker to cross a security boundary.  Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.

A stored cross-site scripting (XSS) vulnerability exists in an undisclosed page of the BIG-IP Configuration utility that allows an attacker to run JavaScript in the context of the currently logged-in user.

An attacker can make the Node.js HTTP/2 server completely unavailable by sending a small amount of HTTP/2 frames packets with a few HTTP/2 frames inside. It is possible to leave some data in nghttp2 memory after reset when headers with HTTP/2 CONTINUATION frame are sent to the server and then a TCP connection is abruptly closed by the client triggering the Http2Session destructor while header frames are still being processed (and stored in memory) causing a race condition.

When the database variable tm.tcpudptxchecksum is configured as non-default value Software-only on a BIG-IP system, undisclosed traffic can cause the Traffic Management Microkernel (TMM) to terminate.

Under undisclosed traffic conditions along with conditions beyond the attacker's control, hardware systems with a High-Speed Bridge (HSB) and an embedded Packet Velocity Acceleration (ePVA) chip may experience a lockup of the HSB.

Fixed bug (1-byte array overrun in common path resolve code). (CVE-2023-0568)

Incorrect IPv4 and IPv6 private ranges

The fix for CVE-2023-24998 was incomplete for Apache Tomcat 11.0.0-M2 to 11.0.0-M4, 10.1.5 to 10.1.7, 9.0.71 to 9.0.73 and 8.5.85 to 8.5.87. If non-default HTTP connector settings were used such that the maxParameterCount could be reached using query string parameters and a request was submitted that supplied exactly maxParameterCount parameters in the query string, the limit for uploaded request parts could be bypassed with the potential for a denial of service to occur.

0-byte UDP payload DoS in c-ares

Validating the order of the public keys in the Diffie-Hellman Key Agreement Protocol, when an approved safe prime is used, allows remote attackers (from the client side) to trigger unnecessarily expensive server-side DHE modular-exponentiation calculations. The client may cause asymmetric resource consumption. The basic attack scenario is that the client must claim that it can only communicate with DHE, and the server must be configured to allow DHE and validate the order of the public key.

The Diffie-Hellman Key Agreement Protocol allows remote attackers (from the client side) to send arbitrary numbers that are actually not public keys, and trigger expensive server-side DHE modular-exponentiation calculations, aka a D(HE)ater attack. The client needs very little CPU resources and network bandwidth. The attack may be more disruptive in cases where a client can require a server to select its largest supported key size. The basic attack scenario is that the client must claim that it can only communicate with DHE, and the server must be configured to allow DHE.The Diffie-Hellman Key Agreement Protocol allows use of long exponents that arguably make certain calculations unnecessarily expensive, because the 1996 van Oorschot and Wiener paper found that "(appropriately) short exponents" can be used when there are adequate subgroup constraints, and these short exponents can lead to less expensive calculations than for long exponents. This issue is different from CVE-2002-20001 because it is based on an observation about exponent size, rather than an observation about numbers that are not public keys. The specific situations in which calculation expense would constitute a server-side vulnerability depend on the protocol (e.g., TLS, SSH, or IKE) and the DHE implementation details. In general, there might be an availability concern because of server-side resource consumption from DHE modular-exponentiation calculations. Finally, it is possible for an attacker to exploit this vulnerability and CVE-2002-20001 together.

Allocation of resources for multipart headers with insufficient limits enabled a DoS vulnerability in Apache Commons FileUpload.

This issue affects Apache Commons FileUpload: from 1.0 before 1.6; from 2.0.0-M1 before 2.0.0-M4.

Users are recommended to upgrade to versions 1.6 or 2.0.0-M4, which fix the issue.

CVE-2024-42516 - this is the "complete" fix for the CVE-2023-38709 response splitting issue. The patch issued upstream for CVE-2023-38709 did not fix the vulnerability.

An HTTP/2 implementation flaw allows a denial-of-service (DoS) that uses malformed HTTP/2 control frames in order to break the max concurrent streams limit (HTTP/2 MadeYouReset Attack).

Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.

Accessibility. A privacy issue was addressed by removing sensitive data.

The c-ares function aresparsenaptrreply(), which is used for parsing NAPTR responses, could be triggered to read memory outside of the given input buffer if the passed in DNS response packet was crafted in a particular way.

A flaw was found in python. An improperly handled HTTP response in the HTTP client code of python may allow a remote attacker, who controls the HTTP server, to make the client script enter an infinite loop, consuming CPU time. The highest threat from this vulnerability is to system availability.

The Diffie-Hellman Key Agreement Protocol allows remote attackers (from the client side) to send arbitrary numbers that are actually not public keys, and trigger expensive server-side DHE modular-exponentiation calculations, aka a D(HE)at or D(HE)ater attack. The client needs very little CPU resources and network bandwidth. The attack may be more disruptive in cases where a client can require a server to select its largest supported key size. The basic attack scenario is that the client must claim that it can only communicate with DHE, and the server must be configured to allow DHE.
