pyasn1 has quadratic CPU use in schemaless BER/CER/DER container decoding

Summary When an application decodes attacker-controlled BER, CER, or DER data without an ASN.1 schema, a container with many distinct long tag IDs can cause quadratic CPU use. Repeated inputs can exhaust CPU and reduce service availability. Details...

SUSE CVE-2026-118664

decode-uri-component provides a more robust alternative to decodeURIComponent. Prior to 0.5.1, decodeUriComponent in index.js falls back to customDecodeURIComponent after native decoding throws, and the fallback collects every distinct percent-encoded run before performing a full-string...

CVE-2026-119194

pyasn1 is a generic ASN.1 library for Python. From 0.3.3 until 0.6.5, schemaless container decoding stores every decoded component's TagSet in a growing set even though only one-versus-multiple tag types must be distinguished. Attacker-controlled BER, CER, or DER input contains many distinct long...

Important: perl-Text-CSV_XS

Issue Overview: Text::CSVXS versions before 1.65 for Perl leak the parsed fields of a record that fails to parse in getline. getline collects the fields of a record into a new array and returns a reference to it only when the parse succeeds. When the record has a syntax error, getline returns und...

CVE-2026-119196 pyasn1: Quadratic CPU consumption in constructed BIT STRING decoding

pyasn1 is a generic ASN.1 library for Python. Prior to 0.6.5, constructed BIT STRING decoding repeatedly shifts and copies the complete bit value accumulated from earlier fragments. Attacker-controlled BER or CER input contains many constructed BIT STRING fragments; schema-driven DER also accepts...

CVE-2026-119194

The pyasn1 Python library (versions 0.3.3 through 0.6.5 ) is vulnerable to a quadratic CPU use issue during schemaless BER, CER, or DER container decoding. The root cause lies in the ConstructedPayloadDecoderBase._decodeComponentsSchemaless function, where the application stores every decoded com...

BIT-PILLOW-2026-96643 Pillow: PNG eXIf chunk makes EXIF parsing run in quadratic time

Pillow is a Python imaging library. From 11.0.0 until 13.0.0, Exif.load in src/PIL/Image.py repeatedly slices the remaining EXIF data while it begins with the six-byte Exif header. src/PIL/PngImagePlugin.py accepts an uncapped PNG eXIf chunk, so a file filled with repeated headers causes a new...

UBUNTU-CVE-2026-118694

python-markdown2 through 2.5.5 contains a denial of service vulnerability that allows remote users to exhaust CPU by submitting Markdown with unclosed inline link destinations. Attackers can submit repeated 'a' or '!a' sequences, causing findbalanced to rescan the remaining document for each link...
