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 •

https://notcve.org/view.php?id=CVE-2021-3621
A flaw was found in SSSD, where the sssctl command was vulnerable to shell command injection via the logs-fetch and cache-expire subcommands. This flaw allows an attacker to trick the root user into running a specially crafted sssctl command, such as via sudo, to gain root access. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability. Se encontró un fallo en SSSD, donde el comando sssctl era vulnerable a la inyección de comandos de shell por medio de los subcomandos logs-fetch y cache-expire.

A flaw was found in postgresql. A purpose-crafted query can read arbitrary bytes of server memory. In the default configuration, any authenticated database user can complete this attack at will. The attack does not require the ability to create objects.
