https://notcve.org/view.php?id=CVE-2020-9383
An issue was discovered in the Linux kernel 3.16 through 5.5.6. set_fdc in drivers/block/floppy.c leads to a wait_til_ready out-of-bounds read because the FDC index is not checked for errors before assigning it, aka CID-2e90ca68b0d2. Se detectó un problema en el kernel de Linux versión 3.16 hasta la versión 5.5.6. La función set_fdc en el archivo drivers/block/floppy.c, conlleva a una lectura fuera de límites de wait_til_ready porque el índice FDC no es comprobado para errores antes de asignarlos, también se conoce como CID-2e90ca68b0d2 An out-of-bounds (OOB) memory access flaw was found in the floppy driver module in the Linux kernel. A bounds check failure allows a local attacker to gain access to out-of-bounds memory leading to a system crash or a leak of internal kernel information. The highest threat from this vulnerability is to system availability. • http://lists.opensuse.org/opensuse-security-announce/2020-03/msg00039.html https://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git/commit/?id=2f9ac30a54dc0181ddac3705cdcf4775d863c530 https://github.com/torvalds/linux/commit/2e90ca68b0d2f5548804f22f0dd61145516171e3 https://lists.debian.org/debian-lts-announce/2020/06/msg00011.html https://lists.debian.org/debian-lts-announce/2020/06/msg00012.html https://lists.debian.org/debian-lts-announce/2020/06/msg00013.html https://security.netapp.com/advisory/ntap& • CWE-125: Out-of-bounds Read •

CVSS: 5.3EPSS: 0%CPEs: 19EXPL: 0CVE-2019-18282 – kernel: The flow_dissector feature allows device tracking
https://notcve.org/view.php?id=CVE-2019-18282
The flow_dissector feature in the Linux kernel 4.3 through 5.x before 5.3.10 has a device tracking vulnerability, aka CID-55667441c84f. This occurs because the auto flowlabel of a UDP IPv6 packet relies on a 32-bit hashrnd value as a secret, and because jhash (instead of siphash) is used. The hashrnd value remains the same starting from boot time, and can be inferred by an attacker. This affects net/core/flow_dissector.c and related code. La función flow_dissector en el kernel de Linux 4.3 a 5.x anterior a la versión 5.3.10 tiene una vulnerabilidad de seguimiento del dispositivo, también conocida como CID-55667441c84f. • https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.3.10 https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=55667441c84fa5e0911a0aac44fb059c15ba6da2 https://lists.debian.org/debian-lts-announce/2020/03/msg00001.html https://security.netapp.com/advisory/ntap-20200204-0002 https://www.computer.org/csdl/proceedings-article/sp/2020/349700b594/1j2LgrHDR2o https://access.redhat.com/security/cve/CVE-2019-18282 https://bugzilla.redhat.com/show_bug.cgi?id=1796360 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-330: Use of Insufficiently Random Values •

https://notcve.org/view.php?id=CVE-2019-17006
In Network Security Services (NSS) before 3.46, several cryptographic primitives had missing length checks. In cases where the application calling the library did not perform a sanity check on the inputs it could result in a crash due to a buffer overflow. En Network Security Services (NSS) versiones anteriores a 3.46, varias primitivas criptográficas presentaban una falta de comprobación de longitud. En los casos en que la aplicación que llama a la biblioteca no llevó a cabo una comprobación de saneo en las entradas, lo que podría resultar en un bloqueo debido a un desbordamiento del búfer A vulnerability was discovered in nss where input text length was not checked when using certain cryptographic primitives. This could lead to a heap-buffer overflow resulting in a crash and data leak. • https://bugzilla.mozilla.org/show_bug.cgi?id=1539788 https://cert-portal.siemens.com/productcert/pdf/ssa-379803.pdf https://developer.mozilla.org/en-US/docs/Mozilla/Projects/NSS/NSS_3.46_release_notes https://security.netapp.com/advisory/ntap-20210129-0001 https://us-cert.cisa.gov/ics/advisories/icsa-21-040-04 https://access.redhat.com/security/cve/CVE-2019-17006 https://bugzilla.redhat.com/show_bug.cgi?id=1775916 • CWE-20: Improper Input Validation CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-122: Heap-based Buffer Overflow •
