https://notcve.org/view.php?id=CVE-2021-43859
01 Feb 2022 — XStream is an open source java library to serialize objects to XML and back again. Versions prior to 1.4.19 may allow a remote attacker to allocate 100% CPU time on the target system depending on CPU type or parallel execution of such a payload resulting in a denial of service only by manipulating the processed input stream. XStream 1.4.19 monitors and accumulates the time it takes to add elements to collections and throws an exception if a set threshold is exceeded. Users are advised to upgrade as soon as ... • http://www.openwall.com/lists/oss-security/2022/02/09/1 • CWE-400: Uncontrolled Resource Consumption CWE-770: Allocation of Resources Without Limits or Throttling •

CVE-2021-4160 – BN_mod_exp may produce incorrect results on MIPS
https://notcve.org/view.php?id=CVE-2021-4160
28 Jan 2022 — There is a carry propagation bug in the MIPS32 and MIPS64 squaring procedure. Many EC algorithms are affected, including some of the TLS 1.3 default curves. Impact was not analyzed in detail, because the pre-requisites for attack are considered unlikely and include reusing private keys. Analysis suggests that attacks against RSA and DSA as a result of this defect would be very difficult to perform and are not believed likely. Attacks against DH are considered just feasible (although very difficult) because ... • https://cert-portal.siemens.com/productcert/pdf/ssa-637483.pdf •

CVE-2022-23990 – expat: integer overflow in the doProlog function
https://notcve.org/view.php?id=CVE-2022-23990
26 Jan 2022 — Expat (aka libexpat) before 2.4.4 has an integer overflow in the doProlog function. Expat (también se conoce como libexpat) versiones anteriores a 2.4.4, presenta un desbordamiento de enteros en la función doProlog A flaw was found in expat. The vulnerability occurs due to large content in element type declarations when there is an element declaration handler present which leads to an integer overflow. This flaw allows an attacker to inject an unsigned integer, leading to a crash or a denial of service.

CVE-2021-22570 – Nullptr Dereference in Protobuf
https://notcve.org/view.php?id=CVE-2021-22570
26 Jan 2022 — Nullptr dereference when a null char is present in a proto symbol. The symbol is parsed incorrectly, leading to an unchecked call into the proto file's name during generation of the resulting error message. Since the symbol is incorrectly parsed, the file is nullptr. We recommend upgrading to version 3.15.0 or greater.

CVE-2021-4034 – Red Hat Polkit Out-of-Bounds Read and Write Vulnerability
https://notcve.org/view.php?id=CVE-2021-4034
25 Jan 2022 — A local privilege escalation vulnerability was found on polkit's pkexec utility. The pkexec application is a setuid tool designed to allow unprivileged users to run commands as privileged users according predefined policies. The current version of pkexec doesn't handle the calling parameters count correctly and ends trying to execute environment variables as commands. An attacker can leverage this by crafting environment variables in such a way it'll induce pkexec to execute arbitrary code.
