CVSS: 7.5EPSS: 0%CPEs: 2EXPL: 0CVE-2021-28677 – python-pillow: Excessive CPU use in EPS image reader
https://notcve.org/view.php?id=CVE-2021-28677
An issue was discovered in Pillow before 8.2.0. For EPS data, the readline implementation used in EPSImageFile has to deal with any combination of \r and \n as line endings. It used an accidentally quadratic method of accumulating lines while looking for a line ending. A malicious EPS file could use this to perform a DoS of Pillow in the open phase, before an image was accepted for opening. Se ha detectado un problema en Pillow versiones anteriores a 8.2.0,. • https://github.com/python-pillow/Pillow/pull/5377 https://lists.debian.org/debian-lts-announce/2021/07/msg00018.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/MQHA5HAIBOYI3R6HDWCLAGFTIQP767FL https://pillow.readthedocs.io/en/stable/releasenotes/8.2.0.html#cve-2021-28677-fix-eps-dos-on-open https://security.gentoo.org/glsa/202107-33 https://access.redhat.com/security/cve/CVE-2021-28677 https://bugzilla.redhat.com/show_bug.cgi?id=1958257 • CWE-20: Improper Input Validation •
