CVSS: 7.4EPSS: 0%CPEs: 35EXPL: 0CVE-2021-20322 – kernel: new DNS Cache Poisoning Attack based on ICMP fragment needed packets replies
https://notcve.org/view.php?id=CVE-2021-20322
A flaw in the processing of received ICMP errors (ICMP fragment needed and ICMP redirect) in the Linux kernel functionality was found to allow the ability to quickly scan open UDP ports. This flaw allows an off-path remote user to effectively bypass the source port UDP randomization. The highest threat from this vulnerability is to confidentiality and possibly integrity, because software that relies on UDP source port randomization are indirectly affected as well. Se encontró un fallo en el procesamiento de los errores ICMP recibidos (fragmento ICMP necesario y redireccionamiento ICMP) en la funcionalidad del kernel de Linux que permite la capacidad de escanear rápidamente los puertos UDP abiertos. Este fallo permite a un usuario remoto fuera de la ruta de acceso omitir efectivamente la aleatorización del puerto de origen UDP. • https://bugzilla.redhat.com/show_bug.cgi?id=2014230 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?h=v5.15-rc6&id=4785305c05b25a242e5314cc821f54ade4c18810 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?h=v5.15-rc6&id=6457378fe796815c973f631a1904e147d6ee33b1 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/net/ipv4/route.c?h=v5.15-rc6&id=67d6d681e15b578c1725bad8ad079e05d1c48a8e https://git.kernel.org/pub/scm/linux/ke • CWE-330: Use of Insufficiently Random Values •
CVSS: 7.5EPSS: 0%CPEs: 44EXPL: 0CVE-2021-45485 – kernel: information leak in the IPv6 implementation
https://notcve.org/view.php?id=CVE-2021-45485
In the IPv6 implementation in the Linux kernel before 5.13.3, net/ipv6/output_core.c has an information leak because of certain use of a hash table which, although big, doesn't properly consider that IPv6-based attackers can typically choose among many IPv6 source addresses. En la implementación de IPv6 en el kernel de Linux versiones anteriores a 5.13.3, el archivo net/ipv6/output_core.c presenta un filtrado de información debido a determinado uso de una tabla hash que, aunque es grande, no considera apropiadamente que atacantes basados en IPv6 pueden elegir típicamente entre muchas direcciones de origen IPv6 An information leak flaw was found in the Linux kernel’s IPv6 implementation in the __ipv6_select_ident in net/ipv6/output_core.c function. The use of a small hash table in IP ID generation allows a remote attacker to reveal sensitive information. • https://arxiv.org/pdf/2112.09604.pdf https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.13.3 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=62f20e068ccc50d6ab66fdb72ba90da2b9418c99 https://security.netapp.com/advisory/ntap-20220121-0001 https://www.oracle.com/security-alerts/cpujul2022.html https://access.redhat.com/security/cve/CVE-2021-45485 https://bugzilla.redhat.com/show_bug.cgi?id=2039911 • CWE-327: Use of a Broken or Risky Cryptographic Algorithm •

lxml is a library for processing XML and HTML in the Python language. Prior to version 4.6.5, the HTML Cleaner in lxml.html lets certain crafted script content pass through, as well as script content in SVG files embedded using data URIs. Users that employ the HTML cleaner in a security relevant context should upgrade to lxml 4.6.5 to receive a patch. There are no known workarounds available. lxml es una biblioteca para procesar XML y HTML en el lenguaje Python.
