{"id":"UBUNTU-CVE-2015-1473","details":"The ADDW macro in stdio-common/vfscanf.c in the GNU C Library (aka glibc or libc6) before 2.21 does not properly consider data-type size during a risk-management decision for use of the alloca function, which might allow context-dependent attackers to cause a denial of service (segmentation violation) or overwrite memory locations beyond the stack boundary via a long line containing wide characters that are improperly handled in a wscanf call.","modified":"2026-02-04T03:24:40.055723Z","published":"2015-02-05T00:00:00Z","related":["USN-2519-1"],"upstream":["CVE-2015-1473"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2015-1473"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-2519-1"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2015-1473"}],"affected":[{"package":{"name":"eglibc","ecosystem":"Ubuntu:14.04:LTS","purl":"pkg:deb/ubuntu/eglibc@2.19-0ubuntu6.6?arch=source&distro=trusty"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.19-0ubuntu6.6"}]}],"versions":["2.17-93ubuntu4","2.18-0ubuntu1","2.18-0ubuntu2","2.18-0ubuntu4","2.18-0ubuntu5","2.18-0ubuntu6","2.18-0ubuntu7","2.19-0ubuntu2","2.19-0ubuntu3","2.19-0ubuntu4","2.19-0ubuntu5","2.19-0ubuntu6","2.19-0ubuntu6.1","2.19-0ubuntu6.3","2.19-0ubuntu6.4","2.19-0ubuntu6.5"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_version":"2.19-0ubuntu6.6","binary_name":"eglibc-source"},{"binary_version":"2.19-0ubuntu6.6","binary_name":"libc-bin"},{"binary_version":"2.19-0ubuntu6.6","binary_name":"libc-dev-bin"},{"binary_version":"2.19-0ubuntu6.6","binary_name":"libc6"},{"binary_version":"2.19-0ubuntu6.6","binary_name":"libc6-amd64"},{"binary_version":"2.19-0ubuntu6.6","binary_name":"libc6-armel"},{"binary_version":"2.19-0ubuntu6.6","binary_name":"libc6-dev"},{"binary_version":"2.19-0ubuntu6.6","binary_name":"libc6-dev-amd64"},{"binary_version":"2.19-0ubuntu6.6","binary_name":"libc6-dev-armel"},{"binary_version":"2.19-0ubuntu6.6","binary_name":"libc6-dev-i386"},{"binary_version":"2.19-0ubuntu6.6","binary_name":"libc6-dev-ppc64"},{"binary_version":"2.19-0ubuntu6.6","binary_name":"libc6-dev-x32"},{"binary_version":"2.19-0ubuntu6.6","binary_name":"libc6-i386"},{"binary_version":"2.19-0ubuntu6.6","binary_name":"libc6-pic"},{"binary_version":"2.19-0ubuntu6.6","binary_name":"libc6-ppc64"},{"binary_version":"2.19-0ubuntu6.6","binary_name":"libc6-prof"},{"binary_version":"2.19-0ubuntu6.6","binary_name":"libc6-x32"},{"binary_version":"2.19-0ubuntu6.6","binary_name":"multiarch-support"},{"binary_version":"2.19-0ubuntu6.6","binary_name":"nscd"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2015/UBUNTU-CVE-2015-1473.json"}}],"schema_version":"1.7.3","severity":[{"type":"Ubuntu","score":"low"}]}
