{"id":"UBUNTU-CVE-2026-114457","details":"A flaw was found in mod_qos. An unauthenticated remote attacker could cause a Denial of Service (DoS) by sending a specially crafted JSON request when JSON body filtering is enabled. Due to improper string termination during the processing of percent-encoded input, the module reads past allocated memory boundaries, which can cause an Apache worker process to crash.","modified":"2026-10-28T20:17:45.296133023Z","published":"2026-10-22T07:16:00Z","upstream":["CVE-2026-114457"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-114457"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-114457"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2558311"}],"affected":[{"package":{"name":"mod-qos","ecosystem":"Ubuntu:26.10","purl":"pkg:deb/ubuntu/mod-qos?arch=source&distro=stonking"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["11.77-1","11.78-1","11.79-1","11.79-1build1"],"ecosystem_specific":{"binaries":[{"binary_version":"11.79-1build1","binary_name":"libapache2-mod-qos"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-114457.json"}},{"package":{"name":"mod-qos","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/mod-qos?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["11.76-4","11.76-5","11.76-6","11.77-1"],"ecosystem_specific":{"binaries":[{"binary_version":"11.77-1","binary_name":"libapache2-mod-qos"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-114457.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L"},{"type":"Ubuntu","score":"medium"}]}
