Background ========== syslog replacement with advanced filtering features. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-admin/syslog-ng < 3.38.1 >= 3.38.1 Description =========== An integer overflow in the RFC3164 parser allows remote attackers to cause a denial of service via crafted syslog input that is mishandled by the tcp or network function. Impact ====== Attackers with access to input syslogs over syslog-ng's network functionality can cause a denial of service. Workaround ========== There is no known workaround at this time. Resolution ========== All syslog-ng users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=app-admin/syslog-ng-3.38.1" References ========== [ 1 ] CVE-2022-38725 https://nvd.nist.gov/vuln/detail/CVE-2022-38725 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: https://security.gentoo.org/glsa/202305-09 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.
