The SafeSocks option in Tor before 0.4.7.13 has a logic error in which the unsafe SOCKS4 protocol can be used but not the safe SOCKS4a protocol, aka TROVE-2022-002. La opción SafeSocks en Tor anterior a 0.4.7.13 tiene un error lógico en el que se puede usar el protocolo SOCKS4 inseguro pero no el protocolo SOCKS4a seguro, también conocido como TROVE-2022-002. • https://gitlab.torproject.org/tpo/core/tor/-/commit/a282145b3634547ab84ccd959d0537c021ff7ffc https://gitlab.torproject.org/tpo/core/tor/-/issues/40730 https://gitlab.torproject.org/tpo/core/tor/-/raw/release-0.4.7/ReleaseNotes https://lists.debian.org/debian-lts-announce/2023/01/msg00026.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/IYOLTP6HQO2HPXUYKOR7P5YYYN7CINQQ https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message •
CVSS: 4.3EPSS: 0%CPEs: 40EXPL: 0CVE-2020-1968 – Raccoon attack
https://notcve.org/view.php?id=CVE-2020-1968
The Raccoon attack exploits a flaw in the TLS specification which can lead to an attacker being able to compute the pre-master secret in connections which have used a Diffie-Hellman (DH) based ciphersuite. In such a case this would result in the attacker being able to eavesdrop on all encrypted communications sent over that TLS connection. The attack can only be exploited if an implementation re-uses a DH secret across multiple TLS connections. Note that this issue only impacts DH ciphersuites and not ECDH ciphersuites. This issue affects OpenSSL 1.0.2 which is out of support and no longer receiving public updates. • https://lists.debian.org/debian-lts-announce/2020/09/msg00016.html https://security.gentoo.org/glsa/202210-02 https://security.netapp.com/advisory/ntap-20200911-0004 https://usn.ubuntu.com/4504-1 https://www.openssl.org/news/secadv/20200909.txt https://www.oracle.com//security-alerts/cpujul2021.html https://www.oracle.com/security-alerts/cpuApr2021.html https://www.oracle.com/security-alerts/cpuapr2022.html https://www.oracle.com/security-alerts/cpujan2021.html https://www.o • CWE-203: Observable Discrepancy •

An issue was discovered in Tor before 0.2.9.15, 0.3.1.x before 0.3.1.10, and 0.3.2.x before 0.3.2.10. The directory-authority protocol-list subprotocol implementation allows remote attackers to cause a denial of service (NULL pointer dereference and directory-authority crash) via a misformatted relay descriptor that is mishandled during voting. Se ha descubierto un problema en Tor en versiones anteriores a la 0.2.9.15, versiones 0.3.1.x anteriores a la 0.3.1.10 y versiones 0.3.2.x anteriores a la 0.3.2.10. La implementación del subprotocolo directory-authority protocol-list permite que atacantes remotos provoquen una denegación de servicio (desreferencia de puntero NULL y cierre inesperado de directory-authority) mediante un descriptor de relevo con formato erróneo que se gestiona de manera incorrecta durante la votación. • https://blog.torproject.org/new-stable-tor-releases-security-fixes-and-dos-prevention-03210-03110-02915 https://trac.torproject.org/projects/tor/ticket/25074 https://www.debian.org/security/2018/dsa-4183 • CWE-476: NULL Pointer Dereference •

Tor before 0.2.8.12 might allow remote attackers to cause a denial of service (client crash) via a crafted hidden service descriptor. Tor, en versiones anteriores a la 0.2.8.12 podría permitir que los atacantes remotos provoquen una denegación de servicio (cierre inesperado del cliente) mediante un descriptor de servicio oculto manipulado. • http://lists.opensuse.org/opensuse-updates/2016-12/msg00154.html http://lists.opensuse.org/opensuse-updates/2016-12/msg00155.html https://blog.torproject.org/blog/tor-02812-released https://gitweb.torproject.org/tor.git/commit/?id=d978216dea6b21ac38230a59d172139185a68dbd https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/FXOJSMCTIOHLBRYFBVEL3CDLGPZXX6WE https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/GTU2R253477RZLYAJAR5DAXAON7KIVLA https://trac. • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

In Tor before 0.2.5.16, 0.2.6 through 0.2.8 before 0.2.8.17, 0.2.9 before 0.2.9.14, 0.3.0 before 0.3.0.13, and 0.3.1 before 0.3.1.9, remote attackers can cause a denial of service (NULL pointer dereference and application crash) against directory authorities via a malformed descriptor, aka TROVE-2017-010. En Tor, en versiones anteriores a la 0.2.5.16; de la versión 0.2.6 hasta la 0.2.8 anterior a la 0.2.8.17, versiones 0.2.9 anteriores a la 0.2.9.14; versiones 0.3.0 anteriores a la 0.3.0.13 y versiones 0.3.1 anteriores a la 0.3.1.9, los atacantes remotos pueden provocar una denegación de servicio (desreferencia de puntero NULL y cierre inesperado de la aplicación) contra autoridades de directorio mediante un descriptor mal formado.
