Synopsis
The remote Amazon Linux 2 host is missing a security update.Description
The version of qpdf installed on the remote host is prior to 5.0.1-4. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2024-2409 advisory.- An issue was discovered in QPDF version 10.0.4, allows remote attackers to execute arbitrary code via crafted .pdf file to Pl_ASCII85Decoder::write parameter in libqpdf. (CVE-2021-25786)
- QPDF 9.x through 9.1.1 and 10.x through 10.0.4 has a heap-based buffer overflow in Pl_ASCII85Decoder::write (called from Pl_AES_PDF::flush and Pl_AES_PDF::finish) when a certain downstream write fails. (CVE-2021-36978)
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
Solution
Run 'yum update qpdf' to update your system.See Also
