https://notcve.org/view.php?id=CVE-2021-3517
19 May 2021 — 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 funcion... • https://bugzilla.redhat.com/show_bug.cgi?id=1954232 • CWE-787: Out-of-bounds Write •
CVSS: 5.9EPSS: 13%CPEs: 205EXPL: 1CVE-2021-3449 – NULL pointer deref in signature_algorithms processing
https://notcve.org/view.php?id=CVE-2021-3449
25 Mar 2021 — An OpenSSL TLS server may crash if sent a maliciously crafted renegotiation ClientHello message from a client. If a TLSv1.2 renegotiation ClientHello omits the signature_algorithms extension (where it was present in the initial ClientHello), but includes a signature_algorithms_cert extension then a NULL pointer dereference will result, leading to a crash and a denial of service attack. A server is only vulnerable if it has TLSv1.2 and renegotiation enabled (which is the default configuration). OpenSSL TLS c... • https://github.com/riptl/cve-2021-3449 • CWE-476: NULL Pointer Dereference •
