CVSS: 8.8EPSS: 2%CPEs: 9EXPL: 0CVE-2020-11100 – haproxy: malformed HTTP/2 requests can lead to out-of-bounds writes
https://notcve.org/view.php?id=CVE-2020-11100
In hpack_dht_insert in hpack-tbl.c in the HPACK decoder in HAProxy 1.8 through 2.x before 2.1.4, a remote attacker can write arbitrary bytes around a certain location on the heap via a crafted HTTP/2 request, possibly causing remote code execution. En la función hpack_dht_insert en el archivo hpack-tbl.c en el decodificador HPACK en HAProxy versiones 1.8 hasta 2.x anteriores a 2.1.4, un atacante remoto puede escribir bytes arbitrarios alrededor de una determinada ubicación en la pila (heap) por medio de una petición HTTP/2 diseñada, causando posiblemente una ejecución de código remoto. A flaw was found in the way HAProxy processed certain HTTP/2 request packets. This flaw allows an attacker to send crafted HTTP/2 request packets, which cause memory corruption, leading to a crash or potential remote arbitrary code execution with the permissions of the user running HAProxy. The haproxy hpack implementation in hpack-tbl.c handles 0-length HTTP headers incorrectly. • http://lists.opensuse.org/opensuse-security-announce/2020-04/msg00002.html http://packetstormsecurity.com/files/157323/haproxy-hpack-tbl.c-Out-Of-Bounds-Write.html http://www.haproxy.org https://bugzilla.redhat.com/show_bug.cgi?id=1819111 https://bugzilla.suse.com/show_bug.cgi?id=1168023 https://git.haproxy.org/?p=haproxy.git%3Ba=commit%3Bh=5dfc5d5cd0d2128d77253ead3acf03a421ab5b88 https://lists.debian.org/debian-security-announce/2020/msg00052.html https://lists.fedoraproject.org/archives/list/packag • CWE-787: Out-of-bounds Write •
CVSS: 8.8EPSS: 0%CPEs: 52EXPL: 6CVE-2020-8835 – Linux kernel bpf verifier vulnerability
https://notcve.org/view.php?id=CVE-2020-8835
In the Linux kernel 5.5.0 and newer, the bpf verifier (kernel/bpf/verifier.c) did not properly restrict the register bounds for 32-bit operations, leading to out-of-bounds reads and writes in kernel memory. The vulnerability also affects the Linux 5.4 stable series, starting with v5.4.7, as the introducing commit was backported to that branch. This vulnerability was fixed in 5.6.1, 5.5.14, and 5.4.29. (issue is aka ZDI-CAN-10780) En el kernel de Linux versiones 5.5.0 y más recientes, el verificador bpf (kernel/bpf/verifier.c) no restringió apropiadamente los límites de registro para operaciones de 32 bits, conllevando a lecturas y escrituras fuera de límites en la memoria del kernel. La vulnerabilidad también afecta a la serie estable de Linux versión 5.4, comenzando con la versión v5.4.7, ya que el commit de introducción fue respaldado en esa derivación. • https://github.com/zilong3033/CVE-2020-8835 https://github.com/digamma-ai/CVE-2020-8835-verification https://github.com/SplendidSky/CVE-2020-8835 https://github.com/Prabhashaka/Exploitation-CVE-2020-8835 https://github.com/johnatag/INF8602-CVE-2020-8835 http://www.openwall.com/lists/oss-security/2021/07/20/1 https://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next.git/commit/?id=f2d67fec0b43edce8c416101cdc52e71145b5fef https://git.kernel.org/pub/scm/linux/kernel/git/torvald • CWE-125: Out-of-bounds Read CWE-787: Out-of-bounds Write •
