If the string to escape contains a very large number of unacceptable characters (which would need escaping), the calculation of the length of the escaped string could overflow, leading to a potential write off the end of the newly allocated string.","published":"2025-11-26T15:15:52.000Z","lastModified":"2026-10-18T20:10:00.000Z","status":"Modified","sourceIdentifier":"secalert@redhat.com","cvss":{"version":"3.1","score":7.7,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H"},"cwe":["CWE-190"],"affected":["redhat/codeready linux builder","redhat/codeready linux builder for ibm z systems","redhat/codeready linux builder for power little endian","redhat/codeready linux builder for x86 64","redhat/enterprise linux for arm 64","redhat/enterprise linux for ibm z systems","redhat/enterprise linux for power little endian","redhat/enterprise linux for x86 64","redhat/codeready linux builder for arm64","redhat/enterprise linux server aus","redhat/codeready linux builder for arm64 eus","redhat/enterprise linux for x86 64 eus","redhat/enterprise linux server for power little endian","redhat/enterprise linux server for power little endian eus","redhat/codeready linux builder for ibm z systems eus","redhat/codeready linux builder for power little endian eus","redhat/codeready linux builder for x86 64 eus","redhat/enterprise linux for arm 64 eus","redhat/enterprise linux for ibm z systems eus","redhat/enterprise linux for power little endian eus","redhat/enterprise linux server tus","redhat/ceph storage","redhat/discovery","gnome/glib","redhat/openshift container platform","redhat/openshift container platform for arm64","redhat/openshift container platform for ibm z","redhat/openshift container platform for linuxone","redhat/openshift container platform for power"],"epss":{"score":0.00322,"percentile":0.25033,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.32%).
