CVE-2019-11500 – dovecot: improper NULL byte handling in IMAP and ManageSieve protocol parsers leads to out of bounds writes
https://notcve.org/view.php?id=CVE-2019-11500
In Dovecot before 2.2.36.4 and 2.3.x before 2.3.7.2 (and Pigeonhole before 0.5.7.2), protocol processing can fail for quoted strings. This occurs because '\0' characters are mishandled, and can lead to out-of-bounds writes and remote code execution. En Dovecot versiones anteriores a 2.2.36.4 y versiones 2.3.x anteriores a 2.3.7.2 (y Pigeonhole versiones anteriores a 0.5.7.2), el procesamiento del protocolo puede fallar para cadenas entre comillas. Esto ocurre porque los caracteres '\0' se manejan inapropiadamente y pueden generar escrituras fuera de límites y ejecución de código remota. A flaw was found in dovecot. • http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00024.html http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00026.html http://www.openwall.com/lists/oss-security/2019/08/28/3 https://access.redhat.com/errata/RHSA-2019:2822 https://access.redhat.com/errata/RHSA-2019:2836 https://access.redhat.com/errata/RHSA-2019:2885 https://dovecot.org/pipermail/dovecot-news/2019-August/000417.html https://lists.debian.org/debian-lts-announce/2019/08/msg00035.html • CWE-20: Improper Input Validation CWE-787: Out-of-bounds Write •
