Background ========== PPP is a Unix implementation of the Point-to-Point Protocol. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-dialup/ppp < 2.4.8 >= 2.4.8 Description =========== It was discovered that bounds check in PPP for the rhostname was improperly constructed in the EAP request and response functions. Impact ====== A remote attacker, by sending specially crafted authentication data, could possibly execute arbitrary code with the privileges of the process or cause a Denial of Service condition. Workaround ========== There is no known workaround at this time. Resolution ========== All PPP users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=net-dialup/ppp-2.4.8" References ========== [ 1 ] CVE-2020-8597 https://nvd.nist.gov/vuln/detail/CVE-2020-8597 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: https://security.gentoo.org/glsa/202003-19 Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users' machines is of utmost importance to us.
