CVE-2019-14813 – ghostscript: Safer mode bypass by .forceput exposure in setsystemparams (701443)
https://notcve.org/view.php?id=CVE-2019-14813
A flaw was found in ghostscript, versions 9.x before 9.50, in the setsystemparams procedure where it did not properly secure its privileged calls, enabling scripts to bypass `-dSAFER` restrictions. A specially crafted PostScript file could disable security protection and then have access to the file system, or execute arbitrary commands. Se detectó un fallo en ghostscript, versiones 9.x versiones anteriores a la 9.50, en el procedimiento setsystemparams donde no aseguraba apropiadamente sus llamadas privilegiadas, permitiendo a los scripts omitir las restricciones "-dSAFER". Un archivo PostScript especialmente diseñado podría deshabilitar la protección de seguridad y entonces tener acceso al sistema de archivos o ejecutar comandos arbitrarios. A flaw was found in the setsystemparams procedure where it did not properly secure its privileged calls, enabling scripts to bypass `-dSAFER` restrictions. • http://git.ghostscript.com/?p=ghostpdl.git%3Ba=commitdiff%3Bh=885444fcbe10dc42787ecb76686c8ee4dd33bf33 http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00088.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00090.html https://access.redhat.com/errata/RHBA-2019:2824 https://access.redhat.com/errata/RHSA-2019:2594 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-14813 https://lists.debian.org/debian-lts-announce/2019/09/msg00007.html https://lists.fedoraproject.o • CWE-648: Incorrect Use of Privileged APIs CWE-863: Incorrect Authorization •
CVE-2019-15807 – kernel: Memory leak in drivers/scsi/libsas/sas_expander.c
https://notcve.org/view.php?id=CVE-2019-15807
In the Linux kernel before 5.1.13, there is a memory leak in drivers/scsi/libsas/sas_expander.c when SAS expander discovery fails. This will cause a BUG and denial of service. En el kernel de Linux versiones anteriores a 5.1.13, se presenta una pérdida de memoria en la biblioteca drivers/scsi/libsas/sas_expander.c cuando no se detecta el expansor SAS. Esto provocará un BUG y una denegación de servicio.

CVE-2019-9506 – Blutooth BR/EDR specification does not specify sufficient encryption key length and allows an attacker to influence key length negotiation
https://notcve.org/view.php?id=CVE-2019-9506
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 •
CVE-2019-10216 – ghostscript: -dSAFER escape via .buildfont1 (701394)
https://notcve.org/view.php?id=CVE-2019-10216
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 •
