CVE-2026-49460

CVE-2026-49460 affects the Python PDF library pypdf . Prior to version 6.12.2 , processing a PDF that uses a stream with the /FlateDecode filter and a PNG predictor can cause unusually long runtimes. The issue is fixed in 6.12.2 . Impact, in line with the sources, is a denial of service-like slow...

GHSA-QPXP-75PX-XJCP pypdf has inefficient decoding of array-based streams

Impact An attacker who uses this vulnerability can craft a PDF which leads to long runtimes and/or large memory usage. This requires accessing an array-based stream with lots of entries. Patches This has been fixed in pypdf==6.9.1. Workarounds If you cannot upgrade yet, consider applying the...

Inefficient Decoding

pypdf is vulnerable to inefficient decoding of ASCIIHexDecode streams. The vulnerability is due to an attacker being able to craft a PDF which leads to long runtimes, where accessing a stream uses the /ASCIIHexDecode filter and can be exploited by attackers to cause a denial of service...

CVE-2026-28804 pypdf: Inefficient decoding of ASCIIHexDecode streams

pypdf is a free and open-source pure-python PDF library. Prior to version 6.7.5, an attacker who uses this vulnerability can craft a PDF which leads to long runtimes. This requires accessing a stream which uses the /ASCIIHexDecode filter. This issue has been patched in version 6.7.5...

CVE-2024-12133

CVE-2024-12133 affects libtasn1 and causes inefficient DER/SEQUENCE OF handling, enabling remote DoS via crafted certificates. Connected advisories confirm affected package libtasn1 and provide mitigations: update to patched libtasn1 versions (e.g., 4.19.x+/4.10.x+ as per distro advisories). If e...

CVE-2024-12133 Libtasn1: inefficient der decoding in libtasn1 leading to potential remote dos

A flaw in libtasn1 causes inefficient handling of specific certificate data. When processing a large number of elements in a certificate, libtasn1 takes much longer than expected, which can slow down or even crash the system. This flaw allows an attacker to send a specially crafted certificate,...
