The udp6_ufo_fragment function in net/ipv6/udp.c in the Linux kernel before 2.6.39, when a certain UDP Fragmentation Offload (UFO) configuration is enabled, allows remote attackers to cause a denial of service (system crash) by sending fragmented IPv6 UDP packets to a bridge device.

An uncontrolled resource consumption vulnerability exists in Citrix ADC <13.0-83.27, <12.1-63.22 and 11.1-65.23 that could allow an attacker with access to NSIP or SNIP with management interface access to cause a temporary disruption of the Management GUI, Nitro API, and RPC communication.

This Metasploit module exploit takes advantage of the StringSubstitutor interpolator class, which is included in the Commons Text library. A default interpolator allows for string lookups that can lead to remote code execution. This is due to a logic flaw that makes the script, dns and url lookup keys interpolated by default, as opposed to what it should be, according to the documentation of the StringLookupFactory class. Those keys allow an attacker to execute arbitrary code via lookups primarily using the script key. In order to exploit the vulnerabilities, the following requirements must be met: Run a version of Apache Commons Text from version 1.5 to 1.9, use the StringSubstitutor interpolator, and the target should run JDK versions prior to 15.

NVIDIA License System contains a vulnerability in the installation scripts for the DLS virtual appliance, where a user on a network after signing in to the portal can access other users’ credentials, allowing them to gain escalated privileges, resulting in limited impact to both confidentiality and integrity.

NVIDIA CUDA Toolkit SDK contains a stack-based buffer overflow vulnerability in cuobjdump, where an unprivileged remote attacker could exploit this buffer overflow condition by persuading a local user to download a specially crafted corrupted file and execute cuobjdump against it locally, which may lead to a limited denial of service and some loss of data integrity for the local user.

Session Validation attacks in Apache Superset versions up to and including 2.0.1. Installations that have not altered the default configured SECRET_KEY according to installation instructions allow for an attacker to authenticate and access unauthorized resources. This does not affect Superset administrators who have changed the default value for SECRET_KEY config.

### Summary An upper bound check issue in `dsaVerify` function allows an attacker to construct signatures that can be successfully verified by any public key, thus leading to a signature forgery attack. ### Details In `dsaVerify` function, it checks whether the value of the signature is legal by calling function `checkValue`, namely, whether `r` and `s` are both in the interval `[1, q - 1]`. However, the second line of the `checkValue` function wrongly checks the upper bound of the passed parameters, since the value of `b.cmp(q)` can only be `0`, `1` and `-1`, and it can never be greater than `q`. In this way, although the values of `s` cannot be `0`, an attacker can achieve the same effect as zero by setting its value to `q`, and then send `(r, s) = (1, q)` to pass the verification of any public key. ### Impact All places in this project that involve DSA verification of user-input signatures will be affected by this vulnerability. ### Fix PR: Since the temporary private fork was...
