UBUNTU-CVE-2026-41991

GNU gzip contains a vulnerability in the gzexe utility related to insecure temporary file handling. When the mktemp utility is not available in the user’s PATH, gzexe falls back to constructing a temporary file path based solely on the process ID PID. This predictable filename is created without...

PYSEC-2026-487 PraisonAIAgents has an OS Command Injection via shell=True in Memory Hooks Executor (memory/hooks.py)

Summary The memory hooks executor in praisonaiagents passes a user-controlled command string directly to subprocess.run with shell=True at src/praisonai-agents/praisonaiagents/memory/hooks.py lines 303 to 305. No sanitization, no shlex.quote, no character filter, and no allowlist check exists...

PYSEC-2026-350 External Control of File Name or Path in h2oai/h2o-3

Remote unauthenticated attackers can overwrite arbitrary server files with attacker-controllable data. The data that the attacker can control is not entirely arbitrary. h2o writes a CSV/XLS/etc file to disk, so the attacker data is wrapped in quotations and starts with "C1", if they're exporting ...

CVE-2026-45257

CVE-2026-45257 : FreeBSD KTLS receive path decrypts in place, enabling an unprivileged local user to overwrite a file’s page cache via sendfile(2) data over a loopback connection when KTLS receive is enabled. This can corrupt the backing file and allow privilege escalation by overwriting setuid/t...

CVE-2026-45257 Arbitrary file overwrite via the KTLS receive path

The KTLS receive path decrypted each record in place, assuming that the mbufs holding received data were anonymous and safe to modify. This assumption does not hold for data placed on a socket by sendfile2, which can reference file-backed memory directly through non-anonymous MEXTPG pages or...
