CVSS: 7.5EPSS: 96%CPEs: 90EXPL: 0CVE-2019-11478 – SACK can cause extensive memory use via fragmented resend queue
https://notcve.org/view.php?id=CVE-2019-11478
Jonathan Looney discovered that the TCP retransmission queue implementation in tcp_fragment in the Linux kernel could be fragmented when handling certain TCP Selective Acknowledgment (SACK) sequences. A remote attacker could use this to cause a denial of service. This has been fixed in stable kernel releases 4.4.182, 4.9.182, 4.14.127, 4.19.52, 5.1.11, and is fixed in commit f070ef2ac66716357066b683fb0baf55f8191a2e. Jonathan Looney descubrió que la implementación de la cola de retransmisión de TCP en tcp_fragment en el kernel de Linux podría estar fragmentada cuando se manejan ciertas secuencias de Reconocimiento Selectivo (SACK) de TCP.

https://notcve.org/view.php?id=CVE-2019-3839
It was found that in ghostscript some privileged operators remained accessible from various places after the CVE-2019-6116 fix. A specially crafted PostScript file could use this flaw in order to, for example, have access to the file system outside of the constrains imposed by -dSAFER. Ghostscript versions before 9.27 are vulnerable. Se econtró una vulnerabilidad en ghostscript, algunos operadores privilegiados permanecían accesibles desde varios lugares después de la corrección CVE-2019-6116. Un archivo especialmente creado de PostScript podría usar este defecto para, por ejemplo, tener acceso al sistema de archivos fuera de las restricciones impuestas por -dSAFER. • http://git.ghostscript.com/?p=ghostpdl.git%3Ba=commitdiff%3Bh=4ec9ca74bed49f2a82acb4bf430eae0d8b3b75c9 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/RHSA-2019:0971 https://access.redhat.com/errata/RHSA-2019:1017 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-3839 https://lists.debian.org/debian-lts-announce/2019/05/msg00023.html https://lists.fedoraproject.or • CWE-648: Incorrect Use of Privileged APIs •
CVSS: 6.5EPSS: 0%CPEs: 30EXPL: 1CVE-2019-3459 – kernel: Heap address information leak while using L2CAP_GET_CONF_OPT
https://notcve.org/view.php?id=CVE-2019-3459
A heap address information leak while using L2CAP_GET_CONF_OPT was discovered in the Linux kernel before 5.1-rc1. Se descubrió una fuga de información de direcciones en memoria dinámica mientras se usaba L2CAP_GET_CONF_OPT en el kernel de Linux anterior a 5.1-rc1. A flaw was found in the Linux kernel's implementation of Logical Link Control and Adaptation Protocol (L2CAP), part of the Bluetooth stack. An attacker, within the range of standard Bluetooth transmissions, can create and send a specially crafted packet. The response to this specially crafted packet can contain part of the kernel stack which can be used in a further attack. • http://www.openwall.com/lists/oss-security/2019/06/27/2 http://www.openwall.com/lists/oss-security/2019/06/27/7 http://www.openwall.com/lists/oss-security/2019/06/28/1 http://www.openwall.com/lists/oss-security/2019/06/28/2 http://www.openwall.com/lists/oss-security/2019/08/12/1 https://access.redhat.com/errata/RHSA-2019:2029 https://access.redhat.com/errata/RHSA-2019:2043 https://access.redhat.com/errata/RHSA-2019:3309 https://access.redhat. • CWE-125: Out-of-bounds Read CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
