A code execution vulnerability exists in the DL_Dxf::handleLWPolylineData functionality of Ribbonsoft dxflib 3.17.0. A specially-crafted .dxf file can lead to a heap buffer overflow. An attacker can provide a malicious file to trigger this vulnerability. Se presenta una vulnerabilidad de ejecución de código en la funcionalidad DL_Dxf::handleLWPolylineData de Ribbonsoft dxflib versión 3.17.0. Un archivo .dxf especialmente diseñado puede conllevar a un desbordamiento del búfer de la pila. • https://lists.debian.org/debian-lts-announce/2022/06/msg00008.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/5BUOTYU3KKIYE4BEBUFA4MRS462P3OWM https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/DA4C4X5GMM65VYLUW7Q7YL6P5NDB633A https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/IMGMEPTYL7WTQ333J6SMC6MUHDMMWT3O https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/L2H36XRMAPQBIOVIIFX6KUT5 • CWE-191: Integer Underflow (Wrap or Wraparound) CWE-787: Out-of-bounds Write •
CVSS: 7.8EPSS: 0%CPEs: 10EXPL: 0CVE-2021-33285 – ntfs-3g: Out-of-bounds heap buffer access in ntfs_get_attribute_value() due to incorrect check of bytes_in_use value in MFT records
https://notcve.org/view.php?id=CVE-2021-33285
In NTFS-3G versions < 2021.8.22, when a specially crafted NTFS attribute is supplied to the function ntfs_get_attribute_value, a heap buffer overflow can occur allowing for memory disclosure or denial of service. The vulnerability is caused by an out-of-bound buffer access which can be triggered by mounting a crafted ntfs partition. The root cause is a missing consistency check after reading an MFT record : the "bytes_in_use" field should be less than the "bytes_allocated" field. When it is not, the parsing of the records proceeds into the wild. En NTFS-3G versiones anteriores a 2021.8.22, cuando es suministrado un atributo NTFS especialmente diseñado a la función ntfs_get_attribute_value, puede ocurrir un desbordamiento del búfer de la pila, permitiendo una divulgación de memoria o una denegación de servicio. • http://www.openwall.com/lists/oss-security/2021/08/30/1 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=988386 https://bugzilla.redhat.com/show_bug.cgi?id=2001608 https://github.com/tuxera/ntfs-3g/security/advisories/GHSA-q759-8j5v-q5jp https://lists.debian.org/debian-lts-announce/2021/11/msg00013.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/766ISTT3KCARKFUIQT7N6WV6T63XOKG3 https://lists.fedoraproject.org/archives/list/package-announce%40lists&# • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2021-39251
A crafted NTFS image can cause a NULL pointer dereference in ntfs_extent_inode_open in NTFS-3G < 2021.8.22. Una imagen NTFS diseñada puede causar una desreferencia de puntero NULL en la función ntfs_extent_inode_open en NTFS-3G versiones anteriores a 2021.8.22 The ntfs3g package is susceptible to an input validation attack. When processing a crafted NTFS image there is an improper check. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability. • http://www.openwall.com/lists/oss-security/2021/08/30/1 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=988386 https://bugzilla.redhat.com/show_bug.cgi?id=2001649 https://github.com/tuxera/ntfs-3g/releases https://github.com/tuxera/ntfs-3g/security/advisories/GHSA-q759-8j5v-q5jp https://lists.debian.org/debian-lts-announce/2021/11/msg00013.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/766ISTT3KCARKFUIQT7N6WV6T63XOKG3 https://lists.f • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-476: NULL Pointer Dereference •
CVSS: 8.1EPSS: 1%CPEs: 7EXPL: 1CVE-2021-40153 – squashfs-tools: unvalidated filepaths allow writing outside of destination
https://notcve.org/view.php?id=CVE-2021-40153
squashfs_opendir in unsquash-1.c in Squashfs-Tools 4.5 stores the filename in the directory entry; this is then used by unsquashfs to create the new file during the unsquash. The filename is not validated for traversal outside of the destination directory, and thus allows writing to locations outside of the destination. La función squashfs_opendir en el archivo unsquash-1.c en Squashfs-Tools versión 4.5, almacena el nombre del archivo en la entrada del directorio; esto es entonces usado por unsquashfs para crear el nuevo archivo durante el desensamblaje. El nombre de archivo no se comprueba para saltar fuera del directorio de destino, y por lo tanto permite escribir en lugares fuera del destino. A flaw was found in Squashfs-tools, where it is vulnerable to attacks similar to zip-slip. • https://bugs.launchpad.net/ubuntu/+source/squashfs-tools/+bug/1941790 https://github.com/plougher/squashfs-tools/commit/79b5a555058eef4e1e7ff220c344d39f8cd09646 https://github.com/plougher/squashfs-tools/issues/72 https://lists.debian.org/debian-lts-announce/2021/08/msg00030.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/GSMRKVJMJFX3MB7D3PXJSYY3TLZROE5S https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/RAOZ4BKWAC4Y3U2K5MMW3S77HWWXHQDL https:&# • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •
CVSS: 6.5EPSS: 0%CPEs: 10EXPL: 0CVE-2021-3634 – libssh: possible heap-based buffer overflow when rekeying
https://notcve.org/view.php?id=CVE-2021-3634
A flaw has been found in libssh in versions prior to 0.9.6. The SSH protocol keeps track of two shared secrets during the lifetime of the session. One of them is called secret_hash and the other session_id. Initially, both of them are the same, but after key re-exchange, previous session_id is kept and used as an input to new secret_hash. Historically, both of these buffers had shared length variable, which worked as long as these buffers were same. • https://bugzilla.redhat.com/show_bug.cgi?id=1978810 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/DRK67AJCWYYVAGF5SGAHNZXCX3PN3ZFP https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/JKYD3ZRAMDAQX3ZW6THHUF3GXN7FF6B4 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/SVWAAB2XMKEUMPMDALINKAA4U2QM4LNG https://security.gentoo.org/glsa/202312-05 https://security.netapp.com/advisory/ntap-20211004-0003 https://www&# • CWE-787: Out-of-bounds Write •
