https://notcve.org/view.php?id=CVE-2022-0711
A flaw was found in the way HAProxy processed HTTP responses containing the "Set-Cookie2" header. This flaw could allow an attacker to send crafted HTTP response packets which lead to an infinite loop, eventually resulting in a denial of service condition. The highest threat from this vulnerability is availability. Se ha encontrado un fallo en la forma en que HAProxy procesa las respuestas HTTP que contienen el encabezado "Set-Cookie2". Este fallo podría permitir a un atacante enviar paquetes de respuesta HTTP diseñados que conllevaran a un bucle infinito, resultando eventualmente en una situación de denegación de servicio. • https://access.redhat.com/security/cve/cve-2022-0711 https://github.com/haproxy/haproxy/commit/bfb15ab34ead85f64cd6da0e9fb418c9cd14cee8 https://www.debian.org/security/2022/dsa-5102 https://www.mail-archive.com/haproxy%40formilux.org/msg41833.html https://access.redhat.com/security/cve/CVE-2022-0711 https://bugzilla.redhat.com/show_bug.cgi?id=2053666 • CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •

An out-of-bounds write issue was found in the VirGL virtual OpenGL renderer (virglrenderer). This flaw allows a malicious guest to create a specially crafted virgil resource and then issue a VIRTGPU_EXECBUFFER ioctl, leading to a denial of service or possible code execution. Se ha encontrado un problema de escritura fuera de límites en el renderizador virtual OpenGL de VirGL (virglrenderer). Este defecto permite a un invitado malicioso crear un recurso virgil especialmente diseñado y luego emitir un ioctl VIRTGPU_EXECBUFFER, conllevando a una denegación de servicio o a una posible ejecución de código. • https://bugzilla.redhat.com/show_bug.cgi?id=2037790 https://lists.debian.org/debian-lts-announce/2022/12/msg00017.html https://security.gentoo.org/glsa/202210-05 • CWE-787: Out-of-bounds Write •
