GHSA-4JHW-X435-X5F7

Vulnerability from github – Published: 2023-10-18 09:30 – Updated: 2024-04-04 08:45
VLAI
Details

In Eclipse Mosquito before and including 2.0.5, establishing a connection to the mosquitto server without sending data causes the EPOLLOUT event to be added, which results excessive CPU consumption. This could be used by a malicious actor to perform denial of service type attack. This issue is fixed in 2.0.6

Vulnerability from github – Published: 2021-09-10 17:54 – Updated: 2021-09-10 16:33
VLAI
Summary
Excessive CPU usage
Details

Envoy, which Pomerium is based on, incorrectly handles resetting of HTTP/2 streams with excessive complexity. This can lead to high CPU utilization when a large number of streams are reset.

Impact

This can result in a DoS condition.

Patches

Pomerium versions 0.14.8 and 0.15.1 contain an upgraded envoy binary with this vulnerability patched.

Workarounds

N/A

Summary
pypdf: Possible long runtimes/large memory usage when extracting XForm objects
Details

Impact

An attacker who uses this vulnerability can craft a PDF which leads to long runtimes and large memory consumption. This requires extracting the text of a page with lots of XForm objects, where some of them might be re-used.

Patches

This has been fixed in pypdf==6.16.1.

Workarounds

If you cannot upgrade yet, consider applying the changes from PR #3966.

The pvscsi_ring_pop_req_descr function in hw/scsi/vmw_pvscsi.c in QEMU (aka Quick Emulator) allows local guest OS administrators to cause a denial of service (infinite loop and QEMU process crash) by leveraging failure to limit process IO loop to the ring size.
