CVSS: 7.8EPSS: 87%CPEs: 56EXPL: 170CVE-2021-4034 – Red Hat Polkit Out-of-Bounds Read and Write Vulnerability
https://notcve.org/view.php?id=CVE-2021-4034
26 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. When successfull... • https://packetstorm.news/files/id/166196 • CWE-20: Improper Input Validation CWE-125: Out-of-bounds Read CWE-787: Out-of-bounds Write •

01 Dec 2021 — NSS (Network Security Services) versions prior to 3.73 or 3.68.1 ESR are vulnerable to a heap overflow when handling DER-encoded DSA or RSA-PSS signatures. Applications using NSS for handling signatures encoded within CMS, S/MIME, PKCS \#7, or PKCS \#12 are likely to be impacted. Applications using NSS for certificate validation or other TLS, X.509, OCSP or CRL functionality may be impacted, depending on how they configure NSS. *Note: This vulnerability does NOT impact Mozilla Firefox.* However, email clien... • https://packetstorm.news/files/id/165110 • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2021-42574
01 Nov 2021 — An issue was discovered in the Bidirectional Algorithm in the Unicode Specification through 14.0. It permits the visual reordering of characters via control sequences, which can be used to craft source code that renders different logic than the logical ordering of tokens ingested by compilers and interpreters. Adversaries can leverage this to encode source code for compilers accepting Unicode such that targeted vulnerabilities are introduced invisibly to human reviewers. NOTE: the Unicode Consortium offers ... • https://github.com/simplylu/CVE-2021-42574 • CWE-94: Improper Control of Generation of Code ('Code Injection') CWE-838: Inappropriate Encoding for Output Context •
