An issue was discovered in Exempi through 2.4.4. XMPFiles/source/FormatSupport/WEBP_Support.cpp does not check whether a bitstream has a NULL value, leading to a NULL pointer dereference in the WEBP::VP8XChunk class. Se ha descubierto un problema en Exempi hasta su versión 2.4.4. XMPFiles/source/FormatSupport/WEBP_Support.cpp no comprueba si un bitstream tiene un valor NULL, lo que conduce a una desreferencia de puntero NULL en la clase WEBP::VP8XChunk. • https://bugs.freedesktop.org/show_bug.cgi?id=105247 https://cgit.freedesktop.org/exempi/commit/?id=aabedb5e749dd59112a3fe1e8e08f2d934f56666 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BCFXKOOATZ2B5G3G7EBXZWVZHEABN4ZV https://usn.ubuntu.com/3668-1 • CWE-476: NULL Pointer Dereference •

CVSS: 7.5EPSS: 96%CPEs: 11EXPL: 2CVE-2018-1000115 – Memcached 1.5.5 - 'Memcrashed' Insufficient Control Network Message Volume Denial of Service
https://notcve.org/view.php?id=CVE-2018-1000115
Memcached version 1.5.5 contains an Insufficient Control of Network Message Volume (Network Amplification, CWE-406) vulnerability in the UDP support of the memcached server that can result in denial of service via network flood (traffic amplification of 1:50,000 has been reported by reliable sources). This attack appear to be exploitable via network connectivity to port 11211 UDP. This vulnerability appears to have been fixed in 1.5.6 due to the disabling of the UDP protocol by default. Memcached 1.5.5 contiene una vulnerabilidad de control insuficiente de volumen de mensaje de red (amplificación de red, CWE-406) en el soporte UDP del servidor memcached que puede resultar en una denegación de servicio (DoS) mediante una inundación de red (fuentes fiables reportan una amplificación de tráfico de 1:50.000). Este ataque parece ser explotable mediante conectividad de red en el puerto UDP 11211. • https://www.exploit-db.com/exploits/44264 https://www.exploit-db.com/exploits/44265 https://access.redhat.com/errata/RHBA-2018:2140 https://access.redhat.com/errata/RHSA-2018:1593 https://access.redhat.com/errata/RHSA-2018:1627 https://access.redhat.com/errata/RHSA-2018:2331 https://access.redhat.com/errata/RHSA-2018:2857 https://blogs.akamai.com/2018/03/memcached-fueled-13-tbps-attacks.html https://github.com/memcached/memcached/commit/dbb7a8af90054bf4ef51f5814ef7ceb17d83d974 https:/ • CWE-400: Uncontrolled Resource Consumption •
