CVSS: 7.5EPSS: 97%CPEs: 96EXPL: 0CVE-2019-11479 – kernel: tcp: excessive resource consumption for TCP connections with low MSS allows remote denial of service
https://notcve.org/view.php?id=CVE-2019-11479
Jonathan Looney discovered that the Linux kernel default MSS is hard-coded to 48 bytes. This allows a remote peer to fragment TCP resend queues significantly more than if a larger MSS were enforced. 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 commits 967c05aee439e6e5d7d805e195b3a20ef5c433d6 and 5f3e2bf008c2221478101ee72f5cb4654b9fc363. Jonathan Looney descubrió que el tamaño máximo de segmento (MSS) por defecto del kernel de Linux está codificado a 48 bytes. • http://www.arubanetworks.com/assets/alert/ARUBA-PSA-2020-010.txt http://www.openwall.com/lists/oss-security/2019/06/28/2 http://www.openwall.com/lists/oss-security/2019/07/06/3 http://www.openwall.com/lists/oss-security/2019/07/06/4 http://www.securityfocus.com/bid/108818 https://access.redhat.com/errata/RHSA-2019:1594 https://access.redhat.com/errata/RHSA-2019:1602 https://access.redhat.com/errata/RHSA-2019:1699 https://access.redhat.com/security/vulnerabili • CWE-400: Uncontrolled Resource Consumption CWE-405: Asymmetric Resource Consumption (Amplification) CWE-770: Allocation of Resources Without Limits or Throttling •

In Wireshark 3.0.0 to 3.0.1, 2.6.0 to 2.6.8, and 2.4.0 to 2.4.14, the dissection engine could crash. This was addressed in epan/packet.c by restricting the number of layers and consequently limiting recursion. En Wireshark versión 3.0.0 a 3.0.1, versión 2.6.0 a 2.6.8 y versión 2.4.0 a 2.4.14, el motor de disección podría fallar. Esto fue direccionado en epan/packet.c por la restricción del número de capas y por consiguiente limitando la recursión. • http://www.securityfocus.com/bid/108464 https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=15778 https://code.wireshark.org/review/gitweb?p=wireshark.git%3Ba=commit%3Bh=7b6e197da4c497e229ed3ebf6952bae5c426a820 https://lists.debian.org/debian-lts-announce/2020/10/msg00036.html https://support.f5.com/csp/article/K06725231 https://support.f5.com/csp/article/K06725231?utm_source=f5support&%3Butm_medium=RSS https://usn.ubuntu.com/4133-1 https://www.wireshark.org/security/wnpa-sec-2019-19.html • CWE-674: Uncontrolled Recursion •
CVSS: 5.9EPSS: 1%CPEs: 180EXPL: 0CVE-2019-1559 – 0-byte record padding oracle
https://notcve.org/view.php?id=CVE-2019-1559
If an application encounters a fatal protocol error and then calls SSL_shutdown() twice (once to send a close_notify, and once to receive one) then OpenSSL can respond differently to the calling application if a 0 byte record is received with invalid padding compared to if a 0 byte record is received with an invalid MAC. If the application then behaves differently based on that in a way that is detectable to the remote peer, then this amounts to a padding oracle that could be used to decrypt data. In order for this to be exploitable "non-stitched" ciphersuites must be in use. Stitched ciphersuites are optimised implementations of certain commonly used ciphersuites. Also the application must call SSL_shutdown() twice even if a protocol error has occurred (applications should not do this but some do anyway). • http://lists.opensuse.org/opensuse-security-announce/2019-03/msg00041.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00019.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00046.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00047.html http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00049.html http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00080.html http://www.securityfocus.com/bid/107174 https://access. • CWE-203: Observable Discrepancy CWE-325: Missing Cryptographic Step •

In Bootstrap before 3.4.1 and 4.3.x before 4.3.1, XSS is possible in the tooltip or popover data-template attribute. En Bootstrap, en versiones anteriores a la 3.4.1 y versiones 4.3.x anteriores a la 4.3.1, es posible Cross-Site Scripting (XSS) en los atributos de data-template tooltip o popover. A cross-site scripting vulnerability was discovered in bootstrap. If an attacker could control the data given to tooltip or popover, they could inject HTML or Javascript into the rendered page when tooltip or popover events fired. • https://github.com/Thampakon/CVE-2019-8331 https://github.com/ossf-cve-benchmark/CVE-2019-8331 https://github.com/Snorlyd/https-nj.gov---CVE-2019-8331 http://packetstormsecurity.com/files/156743/OctoberCMS-Insecure-Dependencies.html http://seclists.org/fulldisclosure/2019/May/10 http://seclists.org/fulldisclosure/2019/May/11 http://seclists.org/fulldisclosure/2019/May/13 http://www.securityfocus.com/bid/107375 https://access.redhat.com/errata/RHSA-2019:1456 https://access.re • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •

https://notcve.org/view.php?id=CVE-2018-13405
The inode_init_owner function in fs/inode.c in the Linux kernel through 3.16 allows local users to create files with an unintended group ownership, in a scenario where a directory is SGID to a certain group and is writable by a user who is not a member of that group. Here, the non-member can trigger creation of a plain file whose group ownership is that group. The intended behavior was that the non-member can trigger creation of a directory (but not a plain file) whose group ownership is that group. The non-member can escalate privileges by making the plain file executable and SGID. La función inode_init_owner en fs/inode.c en el kernel de Linux hasta la versión 3.16 permite a los usuarios locales crear archivos con una propiedad de grupo no deseada, en un escenario donde un directorio es SGID a un cierto grupo y es escribible por un usuario que no es miembro de ese grupo. • https://www.exploit-db.com/exploits/45033 http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=0fa3ecd87848c9c93c2c828ef4c3a8ca36ce46c7 http://openwall.com/lists/oss-security/2018/07/13/2 http://www.securityfocus.com/bid/106503 https://access.redhat.com/errata/RHSA-2018:2948 https://access.redhat.com/errata/RHSA-2018:3083 https://access.redhat.com/errata/RHSA-2018:3096 https://access.redhat.com/errata/RHSA-2019:0717 https://access.redhat.com/errata/RHSA- • CWE-269: Improper Privilege Management CWE-284: Improper Access Control •
