https://notcve.org/view.php?id=CVE-2024-0217
A use-after-free flaw was found in PackageKitd. In some conditions, the order of cleanup mechanics for a transaction could be impacted. As a result, some memory access could occur on memory regions that were previously freed. Once freed, a memory region can be reused for other allocations and any previously stored data in this memory region is considered lost. Se encontró un fallo de use after free en PackageKitd. • https://access.redhat.com/security/cve/CVE-2024-0217 https://bugzilla.redhat.com/show_bug.cgi?id=2256624 https://github.com/PackageKit/PackageKit/commit/64278c9127e3333342b56ead99556161f7e86f79 • CWE-416: Use After Free •

https://notcve.org/view.php?id=CVE-2023-6693
A stack based buffer overflow was found in the virtio-net device of QEMU. This issue occurs when flushing TX in the virtio_net_flush_tx function if guest features VIRTIO_NET_F_HASH_REPORT, VIRTIO_F_VERSION_1 and VIRTIO_NET_F_MRG_RXBUF are enabled. This could allow a malicious user to overwrite local variables allocated on the stack. Specifically, the `out_sg` variable could be used to read a part of process memory and send it to the wire, causing an information leak. Se encontró un desbordamiento de búfer en la región stack de la memoria en el dispositivo virtio-net de QEMU. • https://access.redhat.com/errata/RHSA-2024:2962 https://access.redhat.com/security/cve/CVE-2023-6693 https://bugzilla.redhat.com/show_bug.cgi?id=2254580 https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/OYGUN5HVOXESW7MSNM44E4AE2VNXQB6Y https://security.netapp.com/advisory/ntap-20240208-0004 • CWE-121: Stack-based Buffer Overflow CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2023-6004
A flaw was found in libssh. By utilizing the ProxyCommand or ProxyJump feature, users can exploit unchecked hostname syntax on the client. This issue may allow an attacker to inject malicious code into the command of the features mentioned through the hostname parameter. Se encontró una falla en libssh. Al utilizar la función ProxyCommand o ProxyJump, los usuarios pueden explotar la sintaxis del hostname no verificada en el cliente. • https://access.redhat.com/errata/RHSA-2024:2504 https://access.redhat.com/errata/RHSA-2024:3233 https://access.redhat.com/security/cve/CVE-2023-6004 https://bugzilla.redhat.com/show_bug.cgi?id=2251110 https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/LZQVUHWVWRH73YBXUQJOD6CKHDQBU3DM https://security.netapp.com/advisory/ntap-20240223-0004 https://www.libssh.org/security/advisories/CVE-2023-6004.txt • CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') •

OpenSSH through 9.6, when common types of DRAM are used, might allow row hammer attacks (for authentication bypass) because the integer value of authenticated in mm_answer_authpassword does not resist flips of a single bit. NOTE: this is applicable to a certain threat model of attacker-victim co-location in which the attacker has user privileges. OpenSSH hasta 9.6, cuando se utilizan tipos comunes de DRAM, podría permitir row hammer attacks (para omitir la autenticación) porque el valor entero de autenticado en mm_answer_authpassword no resiste cambios de un solo bit.

CVSS: 5.3EPSS: 0%CPEs: 8EXPL: 6CVE-2023-51764 – postfix: SMTP smuggling vulnerability
https://notcve.org/view.php?id=CVE-2023-51764
Postfix through 3.8.5 allows SMTP smuggling unless configured with smtpd_data_restrictions=reject_unauth_pipelining and smtpd_discard_ehlo_keywords=chunking (or certain other options that exist in recent versions). Remote attackers can use a published exploitation technique to inject e-mail messages with a spoofed MAIL FROM address, allowing bypass of an SPF protection mechanism. This occurs because Postfix supports <LF>.<CR><LF> but some other popular e-mail servers do not. To prevent attack variants (by always disallowing <LF> without <CR>), a different solution is required, such as the smtpd_forbid_bare_newline=yes option with a Postfix minimum version of 3.5.23, 3.6.13, 3.7.9, 3.8.4, or 3.9. • https://github.com/duy-31/CVE-2023-51764 https://github.com/eeenvik1/CVE-2023-51764 https://github.com/Double-q1015/CVE-2023-51764 https://github.com/d4op/CVE-2023-51764-POC http://www.openwall.com/lists/oss-security/2023/12/24/1 http://www.openwall.com/lists/oss-security/2023/12/25/1 http://www.openwall.com/lists/oss-security/2024/05/09/3 https://access.redhat.com/security/cve/CVE-2023-51764 https://bugzilla.redhat.com/show_bug.cgi?id=2255563 http • CWE-345: Insufficient Verification of Data Authenticity CWE-451: User Interface (UI) Misrepresentation of Critical Information •
