log4j-core: DoS in log4j 2.x with thread context message pattern and context lookup pattern (incomplete fix for CVE-2021-44228)
A flaw was found in the Apache Log4j logging library in versions from 2.0.0 and before 2.16.0. A remote attacker with control over Thread Context Map MDC input data could craft malicious input using a JNDI Lookup pattern resulting in remote code execution RCE in a limited number of environments...

DEBIAN-CVE-2025-0677
A flaw was found in grub2. When performing a symlink lookup, the grub's UFS module checks the inode's data size to allocate the internal buffer to read the file content, however, it fails to check if the symlink data size has overflown. When this occurs, grubmalloc may be called with a smaller...
