Unfurl's unbounded zlib decompression allows decompression bomb DoS

SummaryThe compressed data parser uses zlib.decompress without a maximum output size. A small, highly compressed payload can expand to a very large output, causing memory exhaustion and denial of service. Details- unfurl/parsers/parsecompressed.py calls zlib.decompressdecoded with no size limit.-...

perl-IO-Compress: perl-IO-Compress: Arbitrary code execution via attacker-controlled output glob

A flaw was found in perl-IO-Compress, a component used for data compression and decompression. A remote attacker could exploit this vulnerability by crafting a malicious input, specifically an output glob, that bypasses the intended security measures. This could lead to the execution of...
