CVSS: 7.7EPSS: 0%CPEs: 5EXPL: 0CVE-2020-14058 – squid: DoS in TLS handshake
https://notcve.org/view.php?id=CVE-2020-14058
An issue was discovered in Squid before 4.12 and 5.x before 5.0.3. Due to use of a potentially dangerous function, Squid and the default certificate validation helper are vulnerable to a Denial of Service when opening a TLS connection to an attacker-controlled server for HTTPS. This occurs because unrecognized error values are mapped to NULL, but later code expects that each error value is mapped to a valid error string. Se detectó un problema en Squid versiones anteriores a 4.12 y versiones 5.x anteriores a 5.0.3. Debido al uso de una función potencialmente peligrosa, Squid y el asistente de comprobación de certificados predeterminado son vulnerables a una Denegación de Servicio al abrir una conexión TLS en un servidor controlado por el atacante por HTTPS. • http://www.squid-cache.org/Advisories/SQUID-2020_6.txt http://www.squid-cache.org/Versions/v4/changesets/squid-4-93f5fda134a2a010b84ffedbe833d670e63ba4be.patch http://www.squid-cache.org/Versions/v5/changesets/squid-5-c6d1a4f6a2cbebceebc8a3fcd8f539ceb7b7f723.patch https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/3RG5FGSTCAYVIJPJHIY3MRZ7NFT6HDO7 https://security.netapp.com/advisory/ntap-20210312-0001 https://access.redhat.com/security/cve/CVE-2020-14058 https://bugzilla.redhat.com/show • CWE-676: Use of Potentially Dangerous Function •
CVSS: 5.9EPSS: 0%CPEs: 13EXPL: 0CVE-2020-14145 – openssh: Observable discrepancy leading to an information leak in the algorithm negotiation
https://notcve.org/view.php?id=CVE-2020-14145
The client side in OpenSSH 5.7 through 8.4 has an Observable Discrepancy leading to an information leak in the algorithm negotiation. This allows man-in-the-middle attackers to target initial connection attempts (where no host key for the server has been cached by the client). NOTE: some reports state that 8.5 and 8.6 are also affected. El lado del cliente en OpenSSH versiones 5.7 hasta 8.4, presenta una Discrepancia Observable que conlleva a una filtración de información en la negociación del algoritmo. Esto permite a atacantes de tipo man-in-the-middle apuntar a unos intentos iniciales de conexión (donde ninguna clave de host para el servidor ha sido almacenada en caché por parte del cliente) NOTA: algunos informes afirman que las versiones 8.5 y 8.6 también están afectadas. • http://www.openwall.com/lists/oss-security/2020/12/02/1 https://anongit.mindrot.org/openssh.git/commit/?id=b3855ff053f5078ec3d3c653cdaedefaa5fc362d https://docs.ssh-mitm.at/CVE-2020-14145.html https://github.com/openssh/openssh-portable/compare/V_8_3_P1...V_8_4_P1 https://github.com/ssh-mitm/ssh-mitm/blob/master/ssh_proxy_server/plugins/session/cve202014145.py https://security.gentoo.org/glsa/202105-35 https://security.netapp.com/advisory/ntap-20200709-0004 https://www. • CWE-203: Observable Discrepancy •
