Denial of Service (DoS)

Overview Affected versions of this package are vulnerable to Denial of Service DoS via the imagecreatefrombmp process. An attacker can cause excessive memory and CPU consumption by submitting a specially crafted BMP image with large declared dimensions embedded as a data URI in HTML. This can lea...

EUVD-2026-47787

An unauthenticated remote client can cause excessive CPU consumption on a MongoDB server by sending a specific combination of parameters to the awaitable hello command in exhaust mode. The server's handling of this combination results in a response loop that bypasses normal throttling, allowing a...

libssh: libssh: denial of service via zero advertised channel packet size

A flaw was found in libssh. A remote authenticated peer can advertise a zero maximum packet size in SSHMSGCHANNELOPEN, causing later channel writes to loop indefinitely and consume CPU, leading to denial of service...

Linux Distros Unpatched Vulnerability : CVE-2026-63834

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - batman-adv: tpmeter: restrict number of unacked list entries When the unackedlist is unbound, an attacker could send messages with small lengths and appropriate...

python: Python: CPU Denial of Service in HTML parser via repeated unterminated markup declarations

A flaw was found in Python. Its incremental HTML parser can be exploited by a remote attacker. By sending specially crafted, uncontrolled data with repeated, incomplete markup declarations, the attacker can cause the system to consume excessive central processing unit CPU resources. This leads to...

CVE-2026-47736

Puma is a Ruby/Rack web server built for parallelism. From 5.5.0 until 7.2.1 and 8.0.2, when PROXY protocol v1 support is enabled, Puma reads incoming bytes into an internal buffer while waiting for CRLF to determine whether a PROXY v1 line is present, allowing an attacker that continuously sends...

PYSEC-2026-1359 fastapi-guard is vulnerable to ReDoS through inefficient regex

Summary fastapi-guard detects penetration attempts by using regex patterns to scan incoming requests. However, some of the regex patterns used in detection are extremely inefficient and can cause polynomial complexity backtracks when handling specially crafted inputs. It is not as severe as...

PYSEC-2026-1835 pypdf and PyPDF2 possible Infinite Loop when a comment isn't followed by a character

Impact An attacker who uses this vulnerability can craft a PDF which leads to an infinite loop if parsecontentstream is executed. This infinite loop blocks the current process and can utilize a single core of the CPU by 100%. It does not affect memory usage. That is, for example, the case if the...

PYSEC-2026-923 SOAPpy vulnerable to XXE attacks
