The Bluetooth BR/EDR specification up to and including version 5.1 permits sufficiently low encryption key length and does not prevent an attacker from influencing the key length negotiation. This allows practical brute-force attacks (aka "KNOB") that can decrypt traffic and inject arbitrary ciphertext without the victim noticing. La especificación de Bluetooth BR/EDR incluyendo versión 5.1, permite una longitud de clave de cifrado suficientemente baja y no impide que un atacante influya en la negociación de longitud de clave. Esto permite ataques prácticos de fuerza bruta (también se conoce como "KNOB") que pueden descifrar el tráfico e inyectar texto cifrado arbitrario sin que la víctima se dé cuenta. A flaw was discovered in the Bluetooth protocol. • http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00036.html http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00037.html http://seclists.org/fulldisclosure/2019/Aug/11 http://seclists.org/fulldisclosure/2019/Aug/13 http://seclists.org/fulldisclosure/2019/Aug/14 http://seclists.org/fulldisclosure/2019/Aug/15 http://www.cs.ox.ac.uk/publications/publication12404-abstract.html http://www.huawei.com/en/psirt/security-advisories/huawei-sa-20190828-01-knob-en https: • CWE-310: Cryptographic Issues CWE-327: Use of a Broken or Risky Cryptographic Algorithm •

In ghostscript before version 9.50, the .buildfont1 procedure did not properly secure its privileged calls, enabling scripts to bypass `-dSAFER` restrictions. An attacker could abuse this flaw by creating a specially crafted PostScript file that could escalate privileges and access files outside of restricted areas. En ghostscript anterior a la versión 9.50, el procedimiento .buildfont1 no aseguraba adecuadamente sus llamadas privilegiadas, permitiendo que los scripts eludieran las restricciones `-dSAFER`. Un atacante podría abusar de esta fallo al crear un archivo PostScript especialmente diseñado que podría escalar privilegios y acceder a archivos fuera de las áreas restringidas. It was found that the .buildfont1 procedure did not properly secure its privileged calls, enabling scripts to bypass `-dSAFER` restrictions. • http://git.ghostscript.com/?p=ghostpdl.git%3Ba=commitdiff%3Bh=5b85ddd19 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-10216 https://security.gentoo.org/glsa/202004-03 https://access.redhat.com/security/cve/CVE-2019-10216 https://bugzilla.redhat.com/show_bug.cgi?id=1737080 • CWE-648: Incorrect Use of Privileged APIs •

An information disclosure vulnerability exists when certain central processing units (CPU) speculatively access memory. An attacker who successfully exploited the vulnerability could read privileged data across trust boundaries. To exploit this vulnerability, an attacker would have to log on to an affected system and run a specially crafted application. The vulnerability would not allow an attacker to elevate user rights directly, but it could be used to obtain information that could be used to try to compromise the affected system further. On January 3, 2018, Microsoft released an advisory and security updates related to a newly-discovered class of hardware vulnerabilities (known as Spectre) involving speculative execution side channels that affect AMD, ARM, and Intel CPUs to varying degrees. This vulnerability, released on August 6, 2019, is a variant of the Spectre Variant 1 speculative execution side channel vulnerability and has been assigned CVE-2019-1125. Microsoft released a security update on July 9, 2019 that addresses the vulnerability through a software change that mitigates how the CPU speculatively accesses memory. Note that this vulnerability does not require a microcode update from your device OEM. • https://www.exploit-db.com/exploits/48071 http://packetstormsecurity.com/files/156337/SWAPGS-Attack-Proof-Of-Concept.html http://www.huawei.com/en/psirt/security-advisories/huawei-sa-20200408-01-swapgs-en https://access.redhat.com/errata/RHBA-2019:2824 https://access.redhat.com/errata/RHBA-2019:3248 https://access.redhat.com/errata/RHSA-2019:2600 https://access.redhat.com/errata/RHSA-2019:2609 https://access.redhat.com/errata/RHSA-2019:2695 https://access.redhat.com/errata/RHS • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
