CVSS: 7.5EPSS: 0%CPEs: 39EXPL: 0CVE-2021-3697 – grub2: Crafted JPEG image can lead to buffer underflow write in the heap
https://notcve.org/view.php?id=CVE-2021-3697
A crafted JPEG image may lead the JPEG reader to underflow its data pointer, allowing user-controlled data to be written in heap. To a successful to be performed the attacker needs to perform some triage over the heap layout and craft an image with a malicious format and payload. This vulnerability can lead to data corruption and eventual code execution or secure boot circumvention. This flaw affects grub2 versions prior grub-2.12. Una imagen JPEG diseñada puede conllevar que el lector de JPEG desborde su puntero de datos, permitiendo que los datos controlados por el usuario sean escritos en la pila. • https://bugzilla.redhat.com/show_bug.cgi?id=1991687 https://security.gentoo.org/glsa/202209-12 https://security.netapp.com/advisory/ntap-20220930-0001 https://access.redhat.com/security/cve/CVE-2021-3697 • CWE-787: Out-of-bounds Write •
CVSS: 7.8EPSS: 0%CPEs: 14EXPL: 1CVE-2022-1708 – cri-o: memory exhaustion on the node when access to the kube api
https://notcve.org/view.php?id=CVE-2022-1708
A vulnerability was found in CRI-O that causes memory or disk space exhaustion on the node for anyone with access to the Kube API. The ExecSync request runs commands in a container and logs the output of the command. This output is then read by CRI-O after command execution, and it is read in a manner where the entire file corresponding to the output of the command is read in. Thus, if the output of the command is large it is possible to exhaust the memory or the disk space of the node when CRI-O reads the output of the command. The highest threat from this vulnerability is system availability. • https://bugzilla.redhat.com/show_bug.cgi?id=2085361 https://github.com/cri-o/cri-o/commit/f032cf649ecc7e0c46718bd9e7814bfb317cb544 https://github.com/cri-o/cri-o/security/advisories/GHSA-fcm2-6c3h-pg6j https://access.redhat.com/security/cve/CVE-2022-1708 • CWE-400: Uncontrolled Resource Consumption CWE-770: Allocation of Resources Without Limits or Throttling •

https://notcve.org/view.php?id=CVE-2022-1319
A flaw was found in Undertow. For an AJP 400 response, EAP 7 is improperly sending two response packets, and those packets have the reuse flag set even though JBoss EAP closes the connection. A failure occurs when the connection is reused after a 400 by CPING since it reads in the second SEND_HEADERS response packet instead of a CPONG. Se ha encontrado un fallo en Undertow. Para una respuesta AJP 400, EAP 7 envía inapropiadamente el flag de reúso habilitado aunque JBoss EAP cierra la conexión. es producido un fallo cuando la conexión es reusada después de un 400 por CPING ya que lee en el segundo paquete de respuesta SEND_HEADERS en lugar de un CPONG • https://access.redhat.com/security/cve/CVE-2022-1319 https://bugzilla.redhat.com/show_bug.cgi?id=2073890 https://github.com/undertow-io/undertow/commit/1443a1a2bbb8e32e56788109d8285db250d55c8b https://github.com/undertow-io/undertow/commit/7c5b3ab885b5638fd3f1e8a935d5063d68aa2df3 https://issues.redhat.com/browse/UNDERTOW-2060 https://security.netapp.com/advisory/ntap-20221014-0006 • CWE-252: Unchecked Return Value •
