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 •

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. Existe una vulnerabilidad de ejecución de código en la funcionalidad directory rehashing de E2fsprogs e2fsck versión 1.45.4. Un directorio ext4 especialmente diseñado puede causar una escritura fuera de límites en la pila, resultando en una ejecución de código. • http://lists.opensuse.org/opensuse-security-announce/2020-02/msg00004.html https://lists.debian.org/debian-lts-announce/2020/03/msg00030.html https://lists.debian.org/debian-lts-announce/2020/07/msg00021.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/2AKETJ6BREDUHRWQTV35SPGG5C6H7KSI https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/6DOBCYQKCTTWXBLMUPJ5TX3FY7JNCOKY https://security.netapp.com/advisory/ntap-20220506-0001 https://ta • CWE-787: Out-of-bounds Write •

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.

In the Linux kernel before 5.0.6, there is a NULL pointer dereference in drop_sysctl_table() in fs/proc/proc_sysctl.c, related to put_links, aka CID-23da9588037e. En el kernel de Linux versiones anteriores a la versión 5.0.6, hay una desreferencia del puntero NULL en la función drop_sysctl_table() en el archivo fs/proc/proc_sysctl.c, relacionado con put_links, también se conoce como CID-23da9588037e. A flaw was found in the Linux kernel’s implementation of dropping sysctl entries. A local attacker who has access to load modules on the system can trigger a condition during module load failure and panic the system. • http://lists.opensuse.org/opensuse-security-announce/2020-03/msg00021.html https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.0.11 https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.0.6 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=23da9588037ecdd4901db76a5b79a42b529c4ec3 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=89189557b47b35683a27c80ee78aef18248eefb4 https://security.netapp.com/advisory/ntap-20200204-0002 https&# • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-476: NULL Pointer Dereference •
