10 Sep 2020 — get_gate_page in mm/gup.c in the Linux kernel 5.7.x and 5.8.x before 5.8.7 allows privilege escalation because of incorrect reference counting (caused by gate page mishandling) of the struct page that backs the vsyscall page. The result is a refcount underflow. This can be triggered by any 64-bit process that can use ptrace() or process_vm_readv(), aka CID-9fa2dd946743. La función get_gate_page en el archivo mm/gup.c en el kernel de Linux versiones 5.7.x y versiones 5.8.x anteriores a 5.8.7, permite una esc... • http://www.openwall.com/lists/oss-security/2020/09/10/4 • CWE-672: Operation on a Resource after Expiration or Release •

24 Jul 2020 — scp in OpenSSH through 8.3p1 allows command injection in the scp.c toremote function, as demonstrated by backtick characters in the destination argument. NOTE: the vendor reportedly has stated that they intentionally omit validation of "anomalous argument transfers" because that could "stand a great chance of breaking existing workflows." ** EN DISPUTA ** scp en OpenSSH versiones hasta 8.3p1 permite una inyección de comandos en la función toremote de scp.c, como lo demuestran los caracteres backtick en el a... • https://github.com/cpandya2909/CVE-2020-15778 • CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection') CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •

29 Jun 2020 — The client side in OpenSSH 5.7 through 8.4 has an Observable Discrepancy leading to an information leak in the algorithm negotiation. This allows man-in-the-middle attackers to target initial connection attempts (where no host key for the server has been cached by the client).
