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 •
CVSS: 10.0EPSS: 0%CPEs: 21EXPL: 1CVE-2019-17006 – nss: Check length of inputs for cryptographic primitives
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 •

A code execution vulnerability exists in the directory rehashing functionality of E2fsprogs e2fsck 1.45.4. A specially crafted ext4 directory can cause an out-of-bounds write on the stack, resulting in code execution. An attacker can corrupt a partition to trigger this vulnerability.

https://notcve.org/view.php?id=CVE-2019-20095
mwifiex_tm_cmd in drivers/net/wireless/marvell/mwifiex/cfg80211.c in the Linux kernel before 5.1.6 has some error-handling cases that did not free allocated hostcmd memory, aka CID-003b686ace82. This will cause a memory leak and denial of service. La función mwifiex_tm_cmd en el archivo drivers/net/wireless/marvell/mwifiex/cfg80211.c en el kernel de Linux versiones anteriores a la versión 5.1.6 tiene algunos casos de manejo de errores que no liberaron la memoria hostcmd asignada, también se conoce como CID-003b686ace82. Esto causará una pérdida de memoria y una denegación de servicio.
