A flaw was found in mbsync versions prior to 1.4.4. Due to inadequate handling of extremely large (>=2GiB) IMAP literals, malicious or compromised IMAP servers, and hypothetically even external email senders, could cause several different buffer overflows, which could conceivably be exploited for remote code execution. Se ha encontrado un fallo en mbsync versiones anteriores a 1.4.4. Debido al manejo inapropiado de literales IMAP extremadamente grandes ()=2GiB), los servidores IMAP maliciosos o comprometidos, e hipotéticamente incluso los remitentes de correo electrónico externos, podrían causar varios desbordamientos de búfer diferentes, que podrían ser explotados para una ejecución de código remota • https://bugzilla.redhat.com/show_bug.cgi?id=2028932 https://lists.debian.org/debian-lts-announce/2022/07/msg00001.html https://security.gentoo.org/glsa/202208-15 https://www.openwall.com/lists/oss-security/2021/12/03/1 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

https://notcve.org/view.php?id=CVE-2022-0561
Null source pointer passed as an argument to memcpy() function within TIFFFetchStripThing() in tif_dirread.c in libtiff versions from 3.9.0 to 4.3.0 could lead to Denial of Service via crafted TIFF file. For users that compile libtiff from sources, the fix is available with commit eecb0712. Un puntero fuente null pasado como argumento a la función memcpy() dentro de TIFFFetchStripThing() en el archivo tif_dirread.c en libtiff versiones 3.9.0 a 4.3.0, podía conllevar a una denegación de servicio por medio de un archivo TIFF diseñado. Para usuarios que compilan libtiff desde las fuentes, la corrección está disponible con el commit eecb0712 A flaw was found in libtiff where a NULL source pointer passed as an argument to the memcpy() function within the TIFFFetchStripThing() in tif_dirread.c. This flaw allows an attacker with a crafted TIFF file to exploit this flaw, causing a crash and leading to a denial of service. • https://gitlab.com/freedesktop-sdk/mirrors/gitlab/libtiff/libtiff/-/commit/eecb0712f4c3a5b449f70c57988260a667ddbdef https://gitlab.com/gitlab-org/cves/-/blob/master/2022/CVE-2022-0561.json https://gitlab.com/libtiff/libtiff/-/issues/362 https://lists.debian.org/debian-lts-announce/2022/03/msg00001.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/DZEHZ35XVO2VBZ4HHCMM6J6TQIDSBQOM https://security.gentoo.org/glsa/202210-10 https://security.netapp.com/advis • CWE-476: NULL Pointer Dereference •
