CVSS: 5.5EPSS: 0%CPEs: 1EXPL: 0CVE-2021-3429 – sensitive data exposure in cloud-init logs
https://notcve.org/view.php?id=CVE-2021-3429
When instructing cloud-init to set a random password for a new user account, versions before 21.2 would write that password to the world-readable log file /var/log/cloud-init-output.log. This could allow a local user to log in as another user. A flaw was found in cloud-init. When a system is configured through cloud-init and the "Set Passwords" module is used with "chpasswd" directive and "RANDOM", the randomly generated password for the relative user is written in clear-text in a file readable by any existing user of the system. The highest threat from this vulnerability is to data confidentiality and it may allow a local attacker to log in as another user. • https://github.com/canonical/cloud-init/commit/b794d426b9ab43ea9d6371477466070d86e10668 https://access.redhat.com/security/cve/CVE-2021-3429 https://bugzilla.redhat.com/show_bug.cgi?id=1940967 • CWE-532: Insertion of Sensitive Information into Log File •
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 •
