CVE-2021-43818 – HTML Cleaner allows crafted and SVG embedded scripts to pass through
https://notcve.org/view.php?id=CVE-2021-43818
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. En versiones anteriores a 4.6.5, el limpiador de HTML en lxml.html dejaba pasar determinado contenido de scripts manipulados, así como contenido de scripts en archivos SVG insertados usando URIs de datos. • https://github.com/lxml/lxml/commit/12fa9669007180a7bb87d990c375cf91ca5b664a https://github.com/lxml/lxml/commit/a3eacbc0dcf1de1c822ec29fb7d090a4b1712a9c#diff-59130575b4fb2932c957db2922977d7d89afb0b2085357db1a14615a2fcad776 https://github.com/lxml/lxml/commit/f2330237440df7e8f39c3ad1b1aa8852be3b27c0 https://github.com/lxml/lxml/security/advisories/GHSA-55x5-fj6c-h6m8 https://lists.debian.org/debian-lts-announce/2021/12/msg00037.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/TUIS2KE3HZ2AAQKXFLTJFZPP2IFHJTC7 https:/ • CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
CVE-2021-3772 – kernel: sctp: Invalid chunks may be used to remotely remove existing associations
https://notcve.org/view.php?id=CVE-2021-3772
A flaw was found in the Linux SCTP stack. A blind attacker may be able to kill an existing SCTP association through invalid chunks if the attacker knows the IP-addresses and port numbers being used and the attacker can send packets with spoofed IP addresses. Se ha encontrado un fallo en la pila SCTP de Linux. Un atacante ciego puede ser capaz de matar una asociación SCTP existente mediante trozos no válidos si el atacante conoce las direcciones IP y los números de puerto que están siendo usados y el atacante puede enviar paquetes con direcciones IP falsas • https://bugzilla.redhat.com/show_bug.cgi?id=2000694 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=32f8807a48ae55be0e76880cfe8607a18b5bb0df https://github.com/torvalds/linux/commit/32f8807a48ae55be0e76880cfe8607a18b5bb0df https://lists.debian.org/debian-lts-announce/2022/03/msg00012.html https://security.netapp.com/advisory/ntap-20221007-0001 https://ubuntu.com/security/CVE-2021-3772 https://www.debian.org/security/2022/dsa-5096 https://www.oracle.com/security-alerts/cp • CWE-354: Improper Validation of Integrity Check Value •

CVE-2021-43396
https://notcve.org/view.php?id=CVE-2021-43396
In iconvdata/iso-2022-jp-3.c in the GNU C Library (aka glibc) 2.34, remote attackers can force iconv() to emit a spurious '\0' character via crafted ISO-2022-JP-3 data that is accompanied by an internal state reset. This may affect data integrity in certain iconv() use cases. NOTE: the vendor states "the bug cannot be invoked through user input and requires iconv to be invoked with a NULL inbuf, which ought to require a separate application bug to do so unintentionally. Hence there's no security impact to the bug. ** EN DISPUTA ** En el archivo iconvdata/iso-2022-jp-3.c de la Biblioteca C de GNU (también conocida como glibc) 2.34, los atacantes remotos pueden forzar a iconv() a emitir un carácter espurio '\0' a través de datos ISO-2022-JP-3 manipulados que van acompañados de un reinicio de estado interno. Esto puede afectar a la integridad de los datos en ciertos casos de uso de iconv(). • https://blog.tuxcare.com/vulnerability/vulnerability-in-iconv-identified-by-tuxcare-team-cve-2021-43396 https://sourceware.org/bugzilla/show_bug.cgi?id=28524 https://sourceware.org/git/?p=glibc.git%3Ba=commit%3Bh=ff012870b2c02a62598c04daa1e54632e020fd7d https://www.oracle.com/security-alerts/cpujul2022.html •
