In tnef before 1.4.18, an attacker may be able to write to the victim's .ssh/authorized_keys file via an e-mail message with a crafted winmail.dat application/ms-tnef attachment, because of a heap-based buffer over-read involving strdup. En tnef versiones anteriores a 1.4.18, un atacante puede escribir en el archivo .ssh/Authorizedkeys de la víctima por medio de un mensaje de correo electrónico con un archivo adjunto application/ms-tnef de winmail.dat, debido a una lectura excesiva del búfer en la región heap de la memoria que involucra a strdup. • https://github.com/verdammelt/tnef/compare/1.4.17...1.4.18 https://github.com/verdammelt/tnef/pull/40 https://lists.debian.org/debian-lts-announce/2019/11/msg00035.html https://lists.debian.org/debian-lts-announce/2021/08/msg00025.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/RMKFSHPMOZL7MDWU5RYOTIBTRWSZ4Z6X https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/W7CPKBW4QZ4VIY4UXIUVUSHRJ4R2FROE https://usn.ubuntu.c • CWE-125: Out-of-bounds Read •
