CVE-2026-102999: Uncontrolled Resource Consumption

pypdf is a free and open-source pure-python PDF library. Prior to 6.19.0, a crafted PDF containing many embedded files can cause the dictionary-based attachments API in pypdf/doccommon.py to reparse the full attachment list for each content lookup, producing repeated work and long runtimes when a...

github.com/klauspost/compress: klauspost/compress: Denial of Service via integer overflow in dictionary processing

A flaw was found in the klauspost/compress package. A remote attacker can exploit this vulnerability by supplying a specially crafted compression dictionary with an excessively large repeat value, triggering an integer overflow. When the dictionary is subsequently processed, this overflow leads t...
