https://notcve.org/view.php?id=CVE-2018-10846
A cache-based side channel in GnuTLS implementation that leads to plain text recovery in cross-VM attack setting was found. An attacker could use a combination of "Just in Time" Prime+probe attack in combination with Lucky-13 attack to recover plain text using crafted packets. Se ha detectado un canal lateral basado en memoria caché en la implementación GnuTLS que conduce a un ataque de recuperación de texto plano a través de una máquina virtual. Un atacante podría utilizar una combinación de un ataque "Just in Time" Prime+probe con un ataque Lucky-13 para recuperar texto plano usando paquetes manipulados. A cache-based side channel attack was found in the way GnuTLS implements CBC-mode cipher suites. • http://www.securityfocus.com/bid/105138 https://access.redhat.com/errata/RHSA-2018:3050 https://access.redhat.com/errata/RHSA-2018:3505 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-10846 https://eprint.iacr.org/2018/747 https://gitlab.com/gnutls/gnutls/merge_requests/657 https://lists.debian.org/debian-lts-announce/2018/10/msg00022.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/ILMOWPKMTZAIMK5F32TUMO34XCABUCFJ https://lists.fedor • CWE-327: Use of a Broken or Risky Cryptographic Algorithm CWE-385: Covert Timing Channel •

https://notcve.org/view.php?id=CVE-2018-10902
It was found that the raw midi kernel driver does not protect against concurrent access which leads to a double realloc (double free) in snd_rawmidi_input_params() and snd_rawmidi_output_status() which are part of snd_rawmidi_ioctl() handler in rawmidi.c file. A malicious local attacker could possibly use this for privilege escalation. Se ha detectado que el controlador del kernel midi raw no protege contra el acceso concurrente, lo que conduce a un doble realloc (doble liberación) en snd_rawmidi_input_params() y snd_rawmidi_output_status(), que son parte del manipulador snd_rawmidi_ioctl() en el archivo rawmidi.c. Un atacante local malicioso podría utilizarlo para escalar privilegios.
