{"id":"UBUNTU-CVE-2023-44271","details":"An issue was discovered in Pillow before 10.0.0. It is a Denial of Service that uncontrollably allocates memory to process a given task, potentially causing a service to crash by having it run out of memory. This occurs for truetype in ImageFont when textlength in an ImageDraw instance operates on a long text argument.","modified":"2026-04-02T19:29:21.337234323Z","published":"2023-11-03T05:15:00Z","related":["USN-6618-1","USN-8135-1"],"upstream":["CVE-2023-44271"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2023-44271"},{"type":"REPORT","url":"https://devhub.checkmarx.com/cve-details/CVE-2023-44271/"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-6618-1"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2023-44271"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-8135-1"}],"affected":[{"package":{"name":"pillow","ecosystem":"Ubuntu:Pro:14.04:LTS","purl":"pkg:deb/ubuntu/pillow@2.3.0-1ubuntu3.4+esm5?arch=source&distro=esm-infra-legacy/trusty"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.3.0-1ubuntu3.4+esm5"}]}],"versions":["2.2.1-1ubuntu2","2.2.1-2ubuntu1","2.2.1-3ubuntu2","2.2.1-3ubuntu3","2.2.1-3ubuntu4","2.2.1-3ubuntu6","2.3.0-1ubuntu1","2.3.0-1ubuntu2","2.3.0-1ubuntu3","2.3.0-1ubuntu3.2","2.3.0-1ubuntu3.3","2.3.0-1ubuntu3.4","2.3.0-1ubuntu3.4+esm1","2.3.0-1ubuntu3.4+esm2","2.3.0-1ubuntu3.4+esm3","2.3.0-1ubuntu3.4+esm4"],"ecosystem_specific":{"binaries":[{"binary_version":"2.3.0-1ubuntu3.4+esm5","binary_name":"python-imaging"},{"binary_version":"2.3.0-1ubuntu3.4+esm5","binary_name":"python-imaging-compat"},{"binary_version":"2.3.0-1ubuntu3.4+esm5","binary_name":"python-imaging-sane"},{"binary_version":"2.3.0-1ubuntu3.4+esm5","binary_name":"python-imaging-tk"},{"binary_version":"2.3.0-1ubuntu3.4+esm5","binary_name":"python-pil"},{"binary_version":"2.3.0-1ubuntu3.4+esm5","binary_name":"python-pil.imagetk"},{"binary_version":"2.3.0-1ubuntu3.4+esm5","binary_name":"python-sane"},{"binary_version":"2.3.0-1ubuntu3.4+esm5","binary_name":"python3-imaging"},{"binary_version":"2.3.0-1ubuntu3.4+esm5","binary_name":"python3-imaging-sane"},{"binary_version":"2.3.0-1ubuntu3.4+esm5","binary_name":"python3-imaging-tk"},{"binary_version":"2.3.0-1ubuntu3.4+esm5","binary_name":"python3-pil"},{"binary_version":"2.3.0-1ubuntu3.4+esm5","binary_name":"python3-pil.imagetk"},{"binary_version":"2.3.0-1ubuntu3.4+esm5","binary_name":"python3-sane"}],"availability":"Available
