https://notcve.org/view.php?id=CVE-2023-25136
OpenSSH server (sshd) 9.1 introduced a double-free vulnerability during options.kex_algorithms handling. This is fixed in OpenSSH 9.2. The double free can be leveraged, by an unauthenticated remote attacker in the default configuration, to jump to any location in the sshd address space. One third-party report states "remote code execution is theoretically possible." OpenSSH server (sshd) v9.1 introdujo una vulnerabilidad de doble liberación durante el manejo de "options.key_algorithms". • https://github.com/Christbowel/CVE-2023-25136 https://github.com/nhakobyan685/CVE-2023-25136 https://github.com/adhikara13/CVE-2023-25136 https://github.com/jfrog/jfrog-CVE-2023-25136-OpenSSH_Double-Free https://github.com/H4K6/CVE-2023-25136 https://github.com/ticofookfook/CVE-2023-25136 https://github.com/malvika-thakur/CVE-2023-25136 https://github.com/Business1sg00d/CVE-2023-25136 http://www.openwall.com/lists/oss-security/2023/02/13/1 http://www.openwall.com/lists • CWE-401: Missing Release of Memory after Effective Lifetime CWE-415: Double Free •
CVSS: 7.8EPSS: 0%CPEs: 6EXPL: 0CVE-2022-3560 – pesign: Local privilege escalation on pesign systemd service
https://notcve.org/view.php?id=CVE-2022-3560
A flaw was found in pesign. The pesign package provides a systemd service used to start the pesign daemon. This service unit runs a script to set ACLs for /etc/pki/pesign and /run/pesign directories to grant access privileges to users in the 'pesign' group. However, the script doesn't check for symbolic links. This could allow an attacker to gain access to privileged files and directories via a path traversal attack. • https://bugzilla.redhat.com/show_bug.cgi?id=2135420#c0 https://access.redhat.com/security/cve/CVE-2022-3560 https://bugzilla.redhat.com/show_bug.cgi?id=2135420 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •

https://notcve.org/view.php?id=CVE-2022-48303
GNU Tar through 1.34 has a one-byte out-of-bounds read that results in use of uninitialized memory for a conditional jump. Exploitation to change the flow of control has not been demonstrated. The issue occurs in from_header in list.c via a V7 archive in which mtime has approximately 11 whitespace characters. A flaw was found in the Tar package. When attempting to read files with old V7 tar format with a specially crafted checksum, an invalid memory read may occur. • https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/CRY7VEL4AIG3GLIEVCTOXRZNSVYDYYUD https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/X5VQYCO52Z7GAVCLRYUITN7KXHLRZQS4 https://savannah.gnu.org/bugs/?62387 https://savannah.gnu.org/patch/?10307 https://access.redhat.com/security/cve/CVE-2022-48303 https://bugzilla.redhat.com/show_bug.cgi?id=2149722 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-125: Out-of-bounds Read •
