Package : pypdf2
Version : 1.26.0-2+deb9u1
CVE ID : CVE-2022-24859
Debian Bug : 1009879

Sebastian Krause discovered that manipulated inline images can force
PyPDF2, a pure Python PDF library, into an infinite loop, if a maliciously
crafted PDF file is processed.

For Debian 9 stretch, this problem has been fixed in version
1.26.0-2+deb9u1.

We recommend that you upgrade your pypdf2 packages.
