CVE-2021-4160 – BN_mod_exp may produce incorrect results on MIPS
https://notcve.org/view.php?id=CVE-2021-4160
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 most of the work necessary to deduce information about a private key may be performed offline. • https://cert-portal.siemens.com/productcert/pdf/ssa-637483.pdf https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=3bf7b73ea7123045b8f972badc67ed6878e6c37f https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=6fc1aaaf303185aa5e483e06bdfae16daa9193a7 https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=e9e726506cd2a3fd9c0f12daf8cc1fe934c7dddb https://security.gentoo.org/glsa/202210-02 https://security.netapp.com/advisory/ntap-20240621-0006 https://www.debian.org/security/2022/dsa-5103 •
CVE-2022-23181 – Local privilege escalation with FileStore
https://notcve.org/view.php?id=CVE-2022-23181
The fix for bug CVE-2020-9484 introduced a time of check, time of use vulnerability into Apache Tomcat 10.1.0-M1 to 10.1.0-M8, 10.0.0-M5 to 10.0.14, 9.0.35 to 9.0.56 and 8.5.55 to 8.5.73 that allowed a local attacker to perform actions with the privileges of the user that the Tomcat process is using. This issue is only exploitable when Tomcat is configured to persist sessions using the FileStore.

CVE-2022-23990 – expat: integer overflow in the doProlog function
https://notcve.org/view.php?id=CVE-2022-23990
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. • https://cert-portal.siemens.com/productcert/pdf/ssa-484086.pdf https://github.com/libexpat/libexpat/pull/551 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/34NXVL2RZC2YZRV74ZQ3RNFB7WCEUP7D https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/R7FF2UH7MPXKTADYSJUAHI2Y5UHBSHUH https://security.gentoo.org/glsa/202209-24 https://www.debian.org/security/2022/dsa-5073 https://www.oracle.com/security-alerts/cpuapr2022.html https://www. • CWE-190: Integer Overflow or Wraparound •
CVE-2021-4034 – Red Hat Polkit Out-of-Bounds Read and Write Vulnerability
https://notcve.org/view.php?id=CVE-2021-4034
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. When successfully executed the attack can cause a local privilege escalation given unprivileged users administrative rights on the target machine. • https://github.com/dzonerzy/poc-cve-2021-4034 https://github.com/arthepsy/CVE-2021-4034 https://github.com/berdav/CVE-2021-4034 https://www.exploit-db.com/exploits/50689 https://github.com/PwnFunction/CVE-2021-4034 https://github.com/joeammond/CVE-2021-4034 https://github.com/nikaiw/CVE-2021-4034 https://github.com/ryaagard/CVE-2021-4034 https://github.com/Rvn0xsy/CVE-2021-4034 https://github.com/Ayrx/CVE-2021-4034 https://github.com/zhzyker/CVE-2021-4034& • CWE-20: Improper Input Validation CWE-125: Out-of-bounds Read CWE-787: Out-of-bounds Write •
CVE-2021-22570 – Nullptr Dereference in Protobuf
https://notcve.org/view.php?id=CVE-2021-22570
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.
