Allocation of Resources Without Limits or Throttling

Overview Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling in the parselinktext function of mistune/inlineparser.py, which performs a regex search inside a loop that advances one character at a time when parsing fails, producing On² behavior...

EUVD-2026-38854

In the Linux kernel, the following vulnerability has been resolved: netfilter: nfconntracksip: don't use simplestrtoul Replace unsafe port parsing in epaddrlen, ctsipparseheaderuri, and ctsipparserequest with a new sipparseport helper that validates each digit against the buffer limit, eliminatin...

CVE-2026-49851

Mistune is a Python Markdown parser with renderers and plugins. Prior to 3.3.0, Mistune is vulnerable to a CPU exhaustion DoS due to superlinear approximately On² behavior in parselinktext. When parsing Markdown containing many consecutive characters, parselinktext repeatedly scans the input usin...

CVE-2026-49851

Mistune (Python Markdown parser) prior to 3.3.0 is vulnerable to CPU exhaustion DoS due to quadratic-time behavior in parse_link_text when parsing many consecutive '[' characters. The code repeatedly scans input with a regex inside a loop, yielding O(n^2) runtime on affected inputs and enabling a...

In the Linux kernel, the following vulnerability has been resolved: netfilter: nfconntracksip: don't use simplestrtoul Replace unsafe port parsing in epaddrlen, ctsipparseheaderuri, and ctsipparserequest with a new sipparseport helper that validates each digit against the buffer limit, eliminatin...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: ceph: Fix for oops due to invalid pointer for kfree in parselongname This fix addresses a kernel oops that occurs when reading ceph snapshot directories .snap, for example, by simply running ls /mnt/myceph/.snap. The variable str...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: smb/server: Fixed the refcount leak in parsedurablehandlecontext. When the command is a replay operation and -ENOEXEC is returned, the refcount of ksmbdfile must be released...

Astra Linux – Vulnerability in containerd-app

The html.Parse function in golang.org/x/net/html has quadratic parsing complexity when processing certain inputs, which can lead to a Denial-of-Service DoS attack if an attacker provides specially crafted HTML content...

Astra Linux – Vulnerability in protobuf

There is a denial-of-service DoS vulnerability in the google.protobuf.jsonformat.ParseDict function in Python. This vulnerability allows for bypassing the maximum recursion depth when parsing nested google.protobuf.Any messages. Due to the lack of recursion depth accounting within the internal...

CVE-2026-56406

A flaw was found in libexpat. An integer overflow vulnerability exists in the XMLParseBuffer function due to a missing check. This flaw could allow an attacker to cause memory corruption, potentially leading to arbitrary code execution, information disclosure, or a denial of service. Mitigation...

Denial of service via malformed Host header

Impact If this library is used to implement a WebSocket server on top of a TCP server, by using the WebSocket::Driver.server method, then a client can cause the server to crash by sending a Host header that is not a valid host:port string. When this happens, a URI::InvalidURIError exception is...

DEBIAN-CVE-2026-53540

Python-Multipart is a streaming multipart parser for Python. Prior to 0.0.31, parseform did not validate the Content-Length header before using it to bound its chunked read of the request body. A negative Content-Length turned the bounded read into a read-until-EOF, so the entire body was loaded...

CVE-2026-53540

Python-Multipart vulnerability CVE-2026-53540 affects the parse_form function in versions prior to 0.0.31. A negative Content-Length could cause a bounded read to become unbounded, loading the entire request body into memory and potentially exhausting memory. The issue is fixed in 0.0.31; remedia...

CVE-2026-53540 Python-Multipart: Negative Content-Length in parse_form buffers the entire body in memory
