CVE-2019-14889 – libssh: unsanitized location in scp could lead to unwanted command execution
https://notcve.org/view.php?id=CVE-2019-14889
A flaw was found with the libssh API function ssh_scp_new() in versions before 0.9.3 and before 0.8.8. When the libssh SCP client connects to a server, the scp command, which includes a user-provided path, is executed on the server-side. In case the library is used in a way where users can influence the third parameter of the function, it would become possible for an attacker to inject arbitrary commands, leading to a compromise of the remote target. Se detectó un fallo con la función ssh_scp_new() de la API libssh en versiones anteriores a 0.9.3 y anteriores a 0.8.8. Cuando el cliente libssh SCP se conecta a un servidor, el comando scp, que incluye una ruta provista por el usuario, es ejecutado en el lado del servidor. • http://lists.opensuse.org/opensuse-security-announce/2019-12/msg00033.html http://lists.opensuse.org/opensuse-security-announce/2020-01/msg00047.html https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-14889 https://lists.debian.org/debian-lts-announce/2019/12/msg00020.html https://lists.debian.org/debian-lts-announce/2023/05/msg00029.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/7JJWJTXVWLLJTVHBPGWL7472S5FWXYQR https://lists.fedoraproject.org/archives/li • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •
CVE-2019-14870
https://notcve.org/view.php?id=CVE-2019-14870
All Samba versions 4.x.x before 4.9.17, 4.10.x before 4.10.11 and 4.11.x before 4.11.3 have an issue, where the S4U (MS-SFU) Kerberos delegation model includes a feature allowing for a subset of clients to be opted out of constrained delegation in any way, either S4U2Self or regular Kerberos authentication, by forcing all tickets for these clients to be non-forwardable. In AD this is implemented by a user attribute delegation_not_allowed (aka not-delegated), which translates to disallow-forwardable. However the Samba AD DC does not do that for S4U2Self and does set the forwardable flag even if the impersonated client has the not-delegated flag set. Todas las versiones de Samba 4.xx anteriores a 4.9.17, versiones 4.10.x anteriores a 4.10.11 y versiones 4.11.x anteriores a 4.11.3, presentan un problema, donde el modelo de delegación de Kerberos S4U (MS-SFU) incluye una funcionalidad que permite a un subconjunto de clientes ser excluidos de la delegación restringida de cualquier manera, ya sea S4U2Self o autenticación Kerberos regular, al forzar que todos los tickets para estos clientes no sean reenviables. En AD, esto es implementado mediante un atributo de usuario delegation_not_allowed (también se conoce como no delegado), que se traduce como no permitido-reenviable. • http://lists.opensuse.org/opensuse-security-announce/2019-12/msg00038.html https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-14870 https://lists.debian.org/debian-lts-announce/2021/05/msg00023.html https://lists.debian.org/debian-lts-announce/2022/11/msg00034.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/PJH3ROOFYMOATD2UEPC47P5RPBDTY77E https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/WNKA4YIPV7AZR7KK3GW6L3HKGHSGJZFE https: • CWE-285: Improper Authorization CWE-287: Improper Authentication •

In the Linux kernel 5.0.21 and 5.3.11, mounting a crafted btrfs filesystem image, performing some operations, and then making a syncfs system call can lead to a use-after-free in try_merge_free_space in fs/btrfs/free-space-cache.c because the pointer to a left data structure can be the same as the pointer to a right data structure. En el kernel de Linux versiones 5.0.21 y 5.3.11, montando una imagen de sistema de archivos btrfs diseñada, al realizar algunas operaciones y luego haciendo una llamada de sistema syncfs puede conllevar a un uso de la memoria previamente liberada en la función try_merge_free_space en el archivo fs/btrfs/free-space-cache.c porque el puntero en una estructura de datos izquierda puede ser el mismo que el puntero en una estructura de datos derecha. • https://github.com/bobfuzzer/CVE/tree/master/CVE-2019-19448 https://lists.debian.org/debian-lts-announce/2020/09/msg00025.html https://lists.debian.org/debian-lts-announce/2020/10/msg00032.html https://lists.debian.org/debian-lts-announce/2020/10/msg00034.html https://security.netapp.com/advisory/ntap-20200103-0001 https://usn.ubuntu.com/4578-1 • CWE-416: Use After Free •
CVE-2019-1551 – rsaz_512_sqr overflow bug on x86_64
https://notcve.org/view.php?id=CVE-2019-1551
There is an overflow bug in the x64_64 Montgomery squaring procedure used in exponentiation with 512-bit moduli. No EC algorithms are affected. Analysis suggests that attacks against 2-prime RSA1024, 3-prime RSA1536, and DSA1024 as a result of this defect would be very difficult to perform and are not believed likely. Attacks against DH512 are considered just feasible. However, for an attack the target would have to re-use the DH512 private key, which is not recommended anyway. • http://lists.opensuse.org/opensuse-security-announce/2020-01/msg00030.html http://packetstormsecurity.com/files/155754/Slackware-Security-Advisory-openssl-Updates.html https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=419102400a2811582a7a3d4a4e317d72e5ce0a8f https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=f1c5eea8a817075d31e43f5876993c6710238c98 https://lists.debian.org/debian-lts-announce/2022/03/msg00023.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/messag • CWE-190: Integer Overflow or Wraparound •
CVE-2019-17010 – Mozilla: Use-after-free when performing device orientation checks
https://notcve.org/view.php?id=CVE-2019-17010
Under certain conditions, when checking the Resist Fingerprinting preference during device orientation checks, a race condition could have caused a use-after-free and a potentially exploitable crash. This vulnerability affects Thunderbird < 68.3, Firefox ESR < 68.3, and Firefox < 71. Bajo determinadas condiciones, cuando se comprueba la preferencia Resist Fingerprinting durante las verificaciones de orientación del dispositivo, una condición de carrera podría haber causado un uso de la memoria previamente liberada y un bloqueo explotable potencialmente. Esta vulnerabilidad afecta a Thunderbird versiones anteriores a la versión 68.3, Firefox ESR versiones anteriores a la versión 68.3 y Firefox versiones anteriores a la versión 71. • http://lists.opensuse.org/opensuse-security-announce/2020-01/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2020-01/msg00001.html https://access.redhat.com/errata/RHSA-2020:0292 https://access.redhat.com/errata/RHSA-2020:0295 https://bugzilla.mozilla.org/show_bug.cgi?id=1581084 https://security.gentoo.org/glsa/202003-02 https://security.gentoo.org/glsa/202003-10 https://usn.ubuntu.com/4241-1 https://usn.ubuntu.com/4335-1 https://www.mozilla.org/secur • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-416: Use After Free •
