CVSS: 7.5EPSS: 0%CPEs: 49EXPL: 1CVE-2021-22946 – curl: Requirement to use TLS not properly enforced for IMAP, POP3, and FTP protocols
https://notcve.org/view.php?id=CVE-2021-22946
A user can tell curl >= 7.20.0 and <= 7.78.0 to require a successful upgrade to TLS when speaking to an IMAP, POP3 or FTP server (`--ssl-reqd` on the command line or`CURLOPT_USE_SSL` set to `CURLUSESSL_CONTROL` or `CURLUSESSL_ALL` withlibcurl). This requirement could be bypassed if the server would return a properly crafted but perfectly legitimate response.This flaw would then make curl silently continue its operations **withoutTLS** contrary to the instructions and expectations, exposing possibly sensitive data in clear text over the network. Un usuario puede decirle a curl versiones posteriores a 7.20.0 incluyéndola , y versiones anteriores a 7.78.0 incluyéndola, que requiera una actualización con éxito a TLS cuando hable con un servidor IMAP, POP3 o FTP ("--ssl-reqd" en la línea de comandos o "CURLOPT_USE_SSL" configurado como "CURLUSESSL_CONTROL" o "CURLUSESSL_ALL" conlibcurl). Este requisito podría ser omitido si el servidor devolviera una respuesta correctamente diseñada pero perfectamente legítima. Este fallo haría que curl continuara silenciosamente sus operaciones **withoutTLS** en contra de las instrucciones y expectativas, exponiendo posiblemente datos confidenciales en texto sin cifrar a través de la red A flaw was found in curl. • http://seclists.org/fulldisclosure/2022/Mar/29 https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://hackerone.com/reports/1334111 https://lists.debian.org/debian-lts-announce/2021/09/msg00022.html https://lists.debian.org/debian-lts-announce/2022/08/msg00017.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/APOAK4X73EJTAPTSVT7IRVDMUWVXNWGD https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/RWLEC6YVEM2HWUBX67 • CWE-319: Cleartext Transmission of Sensitive Information CWE-325: Missing Cryptographic Step •

The affected application incorrectly neutralizes special elements in a specific HTTP GET request which could lead to command injection. An unauthenticated remote attacker could exploit this vulnerability to execute arbitrary code on the system with root privileges.

CVSS: 8.1EPSS: 0%CPEs: 4EXPL: 1CVE-2021-41072 – squashfs-tools: possible Directory Traversal via symbolic link
https://notcve.org/view.php?id=CVE-2021-41072
squashfs_opendir in unsquash-2.c in Squashfs-Tools 4.5 allows Directory Traversal, a different vulnerability than CVE-2021-40153. A squashfs filesystem that has been crafted to include a symbolic link and then contents under the same filename in a filesystem can cause unsquashfs to first create the symbolic link pointing outside the expected directory, and then the subsequent write operation will cause the unsquashfs process to write through the symbolic link elsewhere in the filesystem. Una función squashfs_opendir en el archivo unsquash-2.c en Squashfs-Tools versión 4.5 permite un Salto de Directorio, una vulnerabilidad diferente a CVE-2021-40153. Un sistema de archivos squashfs que ha sido diseñado para incluir un enlace simbólico y luego contenidos bajo el mismo nombre de archivo en un sistema de archivos puede causar que unsquashfs primero cree el enlace simbólico apuntando fuera del directorio esperado, y luego la operación de escritura subsiguiente causará que el proceso unsquashfs escriba mediante el enlace simbólico en otra parte del sistema de archivos A directory traversal flaw was found in squashfs-tools. During extraction, a file can escape the destination directory by using a symbolic link, and a regular file with an identical name. • https://github.com/plougher/squashfs-tools/commit/e0485802ec72996c20026da320650d8362f555bd https://github.com/plougher/squashfs-tools/issues/72#issuecomment-913833405 https://lists.debian.org/debian-lts-announce/2021/10/msg00017.html https://security.gentoo.org/glsa/202305-29 https://www.debian.org/security/2021/dsa-4987 https://access.redhat.com/security/cve/CVE-2021-41072 https://bugzilla.redhat.com/show_bug.cgi?id=2004957 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') CWE-59: Improper Link Resolution Before File Access ('Link Following') •
