An issue was discovered in the Linux kernel through 5.6.11. sg_write lacks an sg_remove_request call in a certain failure case, aka CID-83c6f2390040. Se detectó un problema en el kernel de Linux versiones hasta 5.6.11. La función sg_write, carece de una llamada a sg_remove_request en un determinado caso de fallo, también se conoce como CID-83c6f2390040. A vulnerability was found in sg_write in drivers/scsi/sg.c in the SCSI generic (sg) driver subsystem. This flaw allows an attacker with local access and special user or root privileges to cause a denial of service if the allocated list is not cleaned with an invalid (Sg_fd * sfp) pointer at the time of failure, also possibly causing a kernel internal information leak problem. • https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=83c6f2390040f188cc25b270b4befeb5628c1aee https://lists.debian.org/debian-lts-announce/2020/06/msg00011.html https://lists.debian.org/debian-lts-announce/2020/06/msg00012.html https://lists.debian.org/debian-lts-announce/2020/06/msg00013.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/ES5C6ZCMALBEBMKNNCTBSLLSYGFZG3FF https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedora • CWE-416: Use After Free •

iproute2 before 5.1.0 has a use-after-free in get_netnsid_from_name in ip/ipnetns.c. NOTE: security relevance may be limited to certain uses of setuid that, although not a default, are sometimes a configuration option offered to end users. Even when setuid is used, other factors (such as C library configuration) may block exploitability. iproute2 versiones anteriores a 5.1.0, presenta un uso de la memoria previamente liberada en la función get_netnsid_from_name en el archivo ip/ipnetns.c. NOTA: la relevancia para la seguridad puede limitarse a ciertos usos del setuid que, aunque no es un valor predeterminado, a veces es una opción de configuración ofrecida a los usuarios finales. Incluso cuando se utiliza setuid, otros factores (como la configuración de la biblioteca C) pueden bloquear la posibilidad de explotación. • https://bugzilla.suse.com/show_bug.cgi?id=1171452 https://git.kernel.org/pub/scm/network/iproute2/iproute2.git/commit/?id=9bf2c538a0eb10d66e2365a655bf6c52f5ba3d10 https://security.gentoo.org/glsa/202008-06 https://usn.ubuntu.com/4357-1 • CWE-416: Use After Free •

json-c through 0.14 has an integer overflow and out-of-bounds write via a large JSON file, as demonstrated by printbuf_memappend. json-c versiones hasta 0.14, presenta un desbordamiento de enteros y una escritura fuera de límites por medio de un archivo JSON grande, como es demostrado por la función printbuf_memappend. A flaw was found in json-c. In printbuf_memappend, certain crafted values can overflow the memory allowing an attacker to write past the memory boundary. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. • https://cert-portal.siemens.com/productcert/pdf/ssa-637483.pdf https://github.com/json-c/json-c/pull/592 https://github.com/rsyslog/libfastjson/issues/161 https://lists.debian.org/debian-lts-announce/2020/05/msg00032.html https://lists.debian.org/debian-lts-announce/2020/05/msg00034.html https://lists.debian.org/debian-lts-announce/2020/07/msg00031.html https://lists.debian.org/debian-lts-announce/2023/06/msg00023.html https://lists.fedoraproject.org/archives/list/package-annou • CWE-190: Integer Overflow or Wraparound CWE-787: Out-of-bounds Write •

In FreeRDP greater than 1.2 and before 2.0.0, a double free in update_read_cache_bitmap_v3_order crashes the client application if corrupted data from a manipulated server is parsed. This has been patched in 2.0.0. En FreeRDP versiones superiores a 1.2 y versiones anteriores a 2.0.0, una doble liberación en update_read_cache_bitmap_v3_order bloquea la aplicación del cliente si los datos corruptos son analizados desde un servidor manipulado. Esto ha sido parcheado en la versión 2.0.0. • https://github.com/FreeRDP/FreeRDP/commit/67c2aa52b2ae0341d469071d1bc8aab91f8d2ed8 https://github.com/FreeRDP/FreeRDP/issues/6013 https://github.com/FreeRDP/FreeRDP/security/advisories/GHSA-cgqh-p732-6x2w https://lists.debian.org/debian-lts-announce/2023/10/msg00008.html https://usn.ubuntu.com/4379-1 https://access.redhat.com/security/cve/CVE-2020-11044 https://bugzilla.redhat.com/show_bug.cgi?id=1835391 • CWE-415: Double Free CWE-672: Operation on a Resource after Expiration or Release •
