CVSS: 8.1EPSS: 10%CPEs: 40EXPL: 2CVE-2021-22901 – curl: Use-after-free in TLS session handling when using OpenSSL TLS backend
https://notcve.org/view.php?id=CVE-2021-22901
curl 7.75.0 through 7.76.1 suffers from a use-after-free vulnerability resulting in already freed memory being used when a TLS 1.3 session ticket arrives over a connection. A malicious server can use this in rare unfortunate circumstances to potentially reach remote code execution in the client. When libcurl at run-time sets up support for TLS 1.3 session tickets on a connection using OpenSSL, it stores pointers to the transfer in-memory object for later retrieval when a session ticket arrives. If the connection is used by multiple transfers (like with a reused HTTP/1.1 connection or multiplexed HTTP/2 connection) that first transfer object might be freed before the new session is established on that connection and then the function will access a memory buffer that might be freed. When using that memory, libcurl might even call a function pointer in the object, making it possible for a remote code execution if the server could somehow manage to get crafted memory content into the correct place in memory. curl versiones 7.75.0 hasta 7.76.1 sufre de una vulnerabilidad de uso de la memoria previamente liberada que resulta en el uso de memoria ya liberada cuando un ticket de sesión TLS 1.3 llega a través de una conexión. • https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://cert-portal.siemens.com/productcert/pdf/ssa-732250.pdf https://curl.se/docs/CVE-2021-22901.html https://github.com/curl/curl/commit/7f4a9a9b2a49547eae24d2e19bc5c346e9026479 https://hackerone.com/reports/1180380 https://security.netapp.com/advisory/ntap-20210723-0001 https://security.netapp.com/advisory/ntap-20210727-0007 https://www.oracle.com//security-alerts/cpujul2021.html https://www.oracle.com/security-alerts/cpuapr2022. • CWE-416: Use After Free •
CVSS: 8.6EPSS: 1%CPEs: 34EXPL: 0CVE-2021-3517 – libxml2: Heap-based buffer overflow in xmlEncodeEntitiesInternal() in entities.c
https://notcve.org/view.php?id=CVE-2021-3517
There is a flaw in the xml entity encoding functionality of libxml2 in versions before 2.9.11. An attacker who is able to supply a crafted file to be processed by an application linked with the affected functionality of libxml2 could trigger an out-of-bounds read. The most likely impact of this flaw is to application availability, with some potential impact to confidentiality and integrity if an attacker is able to use memory information to further exploit the application. Se presenta un fallo en la funcionalidad xml entity encoding de libxml2 en versiones anteriores a 2.9.11. Un atacante que sea capaz de proporcionar un archivo diseñado para que sea procesado por una aplicación vinculada con la funcionalidad afectada de libxml2 podría desencadenar una lectura fuera de los límites. • https://bugzilla.redhat.com/show_bug.cgi?id=1954232 https://lists.apache.org/thread.html/r58af02e294bd07f487e2c64ffc0a29b837db5600e33b6e698b9d696b%40%3Cissues.bookkeeper.apache.org%3E https://lists.apache.org/thread.html/rf4c02775860db415b4955778a131c2795223f61cb8c6a450893651e4%40%3Cissues.bookkeeper.apache.org%3E https://lists.debian.org/debian-lts-announce/2021/05/msg00008.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BZOMV5J4PMZAORVT64BKLV6YIZAFDGX6 https://lists.fedoraproject.org/archives/list/pack • CWE-787: Out-of-bounds Write •

CVSS: 7.6EPSS: 0%CPEs: 5EXPL: 0CVE-2021-29489 – Options structure open to XSS if passed unfiltered
https://notcve.org/view.php?id=CVE-2021-29489
Highcharts JS is a JavaScript charting library based on SVG. In Highcharts versions 8 and earlier, the chart options structure was not systematically filtered for XSS vectors. The potential impact was that content from untrusted sources could execute code in the end user's browser. The vulnerability is patched in version 9. As a workaround, implementers who are not able to upgrade may apply DOMPurify recursively to the options structure to filter out malicious markup. • https://github.com/highcharts/highcharts/security/advisories/GHSA-8j65-4pcq-xq95 https://security.netapp.com/advisory/ntap-20210622-0005 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
