Linux Distros Unpatched Vulnerability : CVE-2026-102994

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - pypdf is a free and open-source pure-python PDF library. Prior to 6.18.0, a crafted PDF containing indirect-object identifiers or generation-number tokens that...

CVE-2026-102994

A flaw was found in pypdf. By supplying a specially crafted PDF document containing excessively long indirect object identifiers or generation tokens without whitespace, a remote attacker can trigger unbounded input scanning during parsing. This issue causes significant processing delays and...

UBUNTU-CVE-2026-102994

pypdf is a free and open-source pure-python PDF library. Prior to 6.18.0, a crafted PDF containing indirect-object identifiers or generation-number tokens that continue for a long time without whitespace can cause pypdf/reader.py and pypdf/generic/base.py to scan excessive input through...

CVE-2026-102994

CVE-2026-102998

The pypdf pure-python PDF library is vulnerable to excessive runtimes in versions prior to 6.19.0 . A crafted PDF containing specific form field values can trigger a loop in pypdf/generic/_appearance_stream.py that repeats invariant selection-data work during appearance-stream generation, particu...

CVE-2026-102998 pypdf: Possible long runtimes when generating appearance streams

pypdf is a free and open-source pure-python PDF library. Prior to 6.19.0, a crafted PDF with form field values can cause pypdf/generic/appearancestream.py appearance-stream generation to repeat invariant selection-data work inside a loop when an application updates fields with flattening enabled,...
