https://notcve.org/view.php?id=CVE-2021-3709
Function check_attachment_for_errors() in file data/general-hooks/ubuntu.py could be tricked into exposing private data via a constructed crash file. This issue affects: apport 2.14.1 versions prior to 2.14.1-0ubuntu3.29+esm8; 2.20.1 versions prior to 2.20.1-0ubuntu2.30+esm2; 2.20.9 versions prior to 2.20.9-0ubuntu7.26; 2.20.11 versions prior to 2.20.11-0ubuntu27.20; 2.20.11 versions prior to 2.20.11-0ubuntu65.3; La función check_attachment_for_errors() en el archivo data/general-hooks/ubuntu.py podría ser engañada para exponer datos privados por medio de un archivo de bloqueo construido. Este problema afecta a: las versiones de apport 2.14.1 anteriores a 2.14.1-0ubuntu3.29+esm8; versiones 2.20.1 anteriores a 2.20.1-0ubuntu2.30+esm2; versiones 2.20.9 anteriores a 2.20.9-0ubuntu7.26; versiones 2.20.11 anteriores a 2.20.11-0ubuntu27.20; versiones 2.20.11 anteriores a 2.20.11-0ubuntu65.3; • https://bugs.launchpad.net/ubuntu/+source/apport/+bug/1934308 https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-3709 https://ubuntu.com/security/notices/USN-5077-1 https://ubuntu.com/security/notices/USN-5077-2 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') CWE-538: Insertion of Sensitive Information into Externally-Accessible File or Directory •
CVSS: 7.8EPSS: 0%CPEs: 15EXPL: 0CVE-2021-3600 – kernel: eBPF 32-bit source register truncation on div/mod
https://notcve.org/view.php?id=CVE-2021-3600
It was discovered that the eBPF implementation in the Linux kernel did not properly track bounds information for 32 bit registers when performing div and mod operations. A local attacker could use this to possibly execute arbitrary code. Se descubrió que la implementación de eBPF en el kernel de Linux no rastreaba adecuadamente la información de límites para registros de 32 bits al realizar operaciones div y mod. Un atacante local podría usar esto para posiblemente ejecutar código arbitrario. A flaw was found in the Linux kernel’s eBPF verification code, where the eBPF 32-bit div/mod source register truncation could lead to out-of-bounds reads and writes. • https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-3600 https://git.kernel.org/linus/e88b2c6e5a4d9ce30d75391e4d950da74bb2bd90 https://ubuntu.com/security/notices/USN-5003-1 https://access.redhat.com/security/cve/CVE-2021-3600 https://bugzilla.redhat.com/show_bug.cgi?id=1981954 • CWE-125: Out-of-bounds Read CWE-787: Out-of-bounds Write •
