CVE-2021-44142 – Samba fruit_pwrite Heap-based Buffer Overflow Remote Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2021-44142
01 Feb 2022 — The Samba vfs_fruit module uses extended file attributes (EA, xattr) to provide "...enhanced compatibility with Apple SMB clients and interoperability with a Netatalk 3 AFP fileserver." Samba versions prior to 4.13.17, 4.14.12 and 4.15.5 with vfs_fruit configured allow out-of-bounds heap read and write via specially crafted extended file attributes. A remote attacker with write access to extended file attributes can execute arbitrary code with the privileges of smbd, typically root.

14 Dec 2021 — It was found that the fix to address CVE-2021-44228 in Apache Log4j 2.15.0 was incomplete in certain non-default configurations. This could allows attackers with control over Thread Context Map (MDC) input data when the logging configuration uses a non-default Pattern Layout with either a Context Lookup (for example, $${ctx:loginId}) or a Thread Context Map pattern (%X, %mdc, or %MDC) to craft malicious input data using a JNDI Lookup pattern resulting in an information leak and remote code execution in some... • https://packetstorm.news/files/id/179987 • CWE-400: Uncontrolled Resource Consumption CWE-917: Improper Neutralization of Special Elements used in an Expression Language Statement ('Expression Language Injection') •

CVE-2021-44228 – Apache Log4j2 Remote Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2021-44228
10 Dec 2021 — Apache Log4j2 2.0-beta9 through 2.15.0 (excluding security releases 2.12.2, 2.12.3, and 2.3.1) JNDI features used in configuration, log messages, and parameters do not protect against attacker controlled LDAP and other JNDI related endpoints. An attacker who can control log messages or log message parameters can execute arbitrary code loaded from LDAP servers when message lookup substitution is enabled. From log4j 2.15.0, this behavior has been disabled by default.
