CVE-2020-3341 – ClamAV PDF Parsing Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3341
A vulnerability in the PDF archive parsing module in Clam AntiVirus (ClamAV) Software versions 0.101 - 0.102.2 could allow an unauthenticated, remote attacker to cause a denial of service condition on an affected device. The vulnerability is due to a stack buffer overflow read. An attacker could exploit this vulnerability by sending a crafted PDF file to an affected device. An exploit could allow the attacker to cause the ClamAV scanning process crash, resulting in a denial of service condition. Una vulnerabilidad en el módulo de análisis de archivos PDF en Clam AntiVirus (ClamAV) Software versiones 0.101 hasta 0.102.2, podría permitir a un atacante no autenticado remoto causar una condición de denegación de servicio sobre un dispositivo afectado. • https://blog.clamav.net/2020/05/clamav-01023-security-patch-released.html https://lists.debian.org/debian-lts-announce/2020/05/msg00018.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/3BMTC7I5LGY4FCIZLHPNC4WWC6VNLFER https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/L5YWYT27SBTV4RZSGFHIQUI4LQVFASWS https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/ROBJOGJOT44MVDX7RQEACYHQN4LYW5RK https://usn.ubuntu.com/ • CWE-20: Improper Input Validation •

CVE-2020-10711 – Kernel: NetLabel: null pointer dereference while receiving CIPSO packet with null category may cause kernel panic
https://notcve.org/view.php?id=CVE-2020-10711
A NULL pointer dereference flaw was found in the Linux kernel's SELinux subsystem in versions before 5.7. This flaw occurs while importing the Commercial IP Security Option (CIPSO) protocol's category bitmap into the SELinux extensible bitmap via the' ebitmap_netlbl_import' routine. While processing the CIPSO restricted bitmap tag in the 'cipso_v4_parsetag_rbm' routine, it sets the security attribute to indicate that the category bitmap is present, even if it has not been allocated. This issue leads to a NULL pointer dereference issue while importing the same category bitmap into SELinux. This flaw allows a remote network user to crash the system kernel, resulting in a denial of service. • http://lists.opensuse.org/opensuse-security-announce/2020-06/msg00022.html http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00008.html https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2020-10711 https://lists.debian.org/debian-lts-announce/2020/06/msg00012.html https://security.netapp.com/advisory/ntap-20200608-0001 https://usn.ubuntu.com/4411-1 https://usn.ubuntu.com/4412-1 https://usn.ubuntu.com/4413-1 https://usn.ubuntu.com/4414-1 https://usn.ubuntu& • CWE-476: NULL Pointer Dereference •
