https://notcve.org/view.php?id=CVE-2022-0435
A stack overflow flaw was found in the Linux kernel's TIPC protocol functionality in the way a user sends a packet with malicious content where the number of domain member nodes is higher than the 64 allowed. This flaw allows a remote user to crash the system or possibly escalate their privileges if they have access to the TIPC network.

https://notcve.org/view.php?id=CVE-2021-44142
The Samba vfs_fruit module uses extended file attributes (EA, xattr) to provide "...enhanced compatibility with Apple SMB clients and interoperability with a Netatalk 3 AFP fileserver." Samba versions prior to 4.13.17, 4.14.12 and 4.15.5 with vfs_fruit configured allow out-of-bounds heap read and write via specially crafted extended file attributes. A remote attacker with write access to extended file attributes can execute arbitrary code with the privileges of smbd, typically root. El módulo vfs_fruit de Samba usa atributos de archivo extendidos (EA, xattr) para proporcionar "...compatibilidad mejorada con los clientes SMB de Apple e interoperabilidad con un servidor de archivos AFP de Netatalk 3". Samba versiones anteriores a 4.13.17, 4.14.12 y 4.15.5 con vfs_fruit configurado permiten una lectura y escritura fuera de límites de la pila por medio de atributos de archivo extendidos especialmente diseñados. • https://github.com/horizon3ai/CVE-2021-44142 https://github.com/gudyrmik/CVE-2021-44142 https://github.com/hrsman/Samba-CVE-2021-44142 https://bugzilla.samba.org/show_bug.cgi?id=14914 https://kb.cert.org/vuls/id/119678 https://security.gentoo.org/glsa/202309-06 https://www.samba.org/samba/security/CVE-2021-44142.html https://www.zerodayinitiative.com/blog/2022/2/1/cve-2021-44142-details-on-a-samba-code-execution-bug-demonstrated-at-pwn2own-austin https://access.redhat&# • CWE-125: Out-of-bounds Read CWE-787: Out-of-bounds Write •
CVSS: 7.8EPSS: 0%CPEs: 56EXPL: 33CVE-2021-4034 – Red Hat Polkit Out-of-Bounds Read and Write Vulnerability
https://notcve.org/view.php?id=CVE-2021-4034
A local privilege escalation vulnerability was found on polkit's pkexec utility. The pkexec application is a setuid tool designed to allow unprivileged users to run commands as privileged users according predefined policies. The current version of pkexec doesn't handle the calling parameters count correctly and ends trying to execute environment variables as commands. An attacker can leverage this by crafting environment variables in such a way it'll induce pkexec to execute arbitrary code. When successfully executed the attack can cause a local privilege escalation given unprivileged users administrative rights on the target machine. • https://github.com/dzonerzy/poc-cve-2021-4034 https://github.com/arthepsy/CVE-2021-4034 https://github.com/berdav/CVE-2021-4034 https://www.exploit-db.com/exploits/50689 https://github.com/PwnFunction/CVE-2021-4034 https://github.com/joeammond/CVE-2021-4034 https://github.com/nikaiw/CVE-2021-4034 https://github.com/ryaagard/CVE-2021-4034 https://github.com/Rvn0xsy/CVE-2021-4034 https://github.com/Ayrx/CVE-2021-4034 https://github.com/zhzyker/CVE-2021-4034& • CWE-20: Improper Input Validation CWE-125: Out-of-bounds Read CWE-787: Out-of-bounds Write •
