CVE-2021-35517 – Apache Commons Compress 1.1 to 1.20 denial of service vulnerability
https://notcve.org/view.php?id=CVE-2021-35517
When reading a specially crafted TAR archive, Compress can be made to allocate large amounts of memory that finally leads to an out of memory error even for very small inputs. This could be used to mount a denial of service attack against services that use Compress' tar package.

CVE-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 •
