CVE-2020-3327 – ClamAV ARJ Archive Parsing Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3327
A vulnerability in the ARJ archive parsing module in Clam AntiVirus (ClamAV) Software versions 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 heap buffer overflow read. An attacker could exploit this vulnerability by sending a crafted ARJ 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 ARJ en Clam AntiVirus (ClamAV) Software versiones 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.debian.org/debian-lts-announce/2020/08/msg00010.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/IJ67VH37NCG25PICGWFWZHSVG7PBT7MC https://lists.fedoraproject.org/archives/list/package-announce%40lists.f • CWE-20: Improper Input Validation •

CVE-2020-11931 – Ubuntu modifications to pulseaudio to provide snap security enforcement could be unloaded
https://notcve.org/view.php?id=CVE-2020-11931
An Ubuntu-specific modification to Pulseaudio to provide security mediation for Snap-packaged applications was found to have a bypass of intended access restriction for snaps which plugs any of pulseaudio, audio-playback or audio-record via unloading the pulseaudio snap policy module. This issue affects: pulseaudio 1:8.0 versions prior to 1:8.0-0ubuntu3.12; 1:11.1 versions prior to 1:11.1-1ubuntu7.7; 1:13.0 versions prior to 1:13.0-1ubuntu1.2; 1:13.99.1 versions prior to 1:13.99.1-1ubuntu3.2; Una modificación específica de Ubuntu para Pulseaudio para proporcionar mediación de seguridad para aplicaciones empaquetadas de Snap se encontró que presenta una omisión de la restricción de acceso prevista para los snaps que conecta cualquiera pulseaudio, audio-playback o audio-record mediante la descarga del módulo de la política de snap de pulseaudio. Este problema afecta a: pulseaudio versiones 1:8.0 anteriores a 1:8.0-0ubuntu3.12; versiones 1:11.1 anteriores a 1:11.1-1ubuntu7.7; versiones 1:13.0 anteriores a 1:13.0-1ubuntu1.2; versiones 1:13.99.1 anteriores a 1:13.99.1-1ubuntu3.2; • https://forum.snapcraft.io/t/audio-switcher-pulseaudio-interface-auto-connect-request/16648/3 https://usn.ubuntu.com/4355-1 • CWE-284: Improper Access Control CWE-668: Exposure of Resource to Wrong Sphere •
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 •
CVE-2020-12826 – kernel: possible to send arbitrary signals to a privileged (suidroot) parent process
https://notcve.org/view.php?id=CVE-2020-12826
A signal access-control issue was discovered in the Linux kernel before 5.6.5, aka CID-7395ea4e65c2. Because exec_id in include/linux/sched.h is only 32 bits, an integer overflow can interfere with a do_notify_parent protection mechanism. A child process can send an arbitrary signal to a parent process in a different security domain. Exploitation limitations include the amount of elapsed time before an integer overflow occurs, and the lack of scenarios where signals to a parent process present a substantial operational threat. Se detectó un problema de control de acceso de señal en el kernel de Linux versiones anteriores a 5.6.5, se conoce como CID-7395ea4e65c2. • https://bugzilla.redhat.com/show_bug.cgi?id=1822077 https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.6.5 https://github.com/torvalds/linux/commit/7395ea4e65c2a00d23185a3f63ad315756ba9cef https://lists.debian.org/debian-lts-announce/2020/06/msg00011.html https://lists.debian.org/debian-lts-announce/2020/06/msg00013.html https://lists.openwall.net/linux-kernel/2020/03/24/1803 https://security.netapp.com/advisory/ntap-20200608-0001 https://usn.ubuntu.com/4367-1 https://u • CWE-94: Improper Control of Generation of Code ('Code Injection') CWE-190: Integer Overflow or Wraparound •
