pypdf is a free and open-source pure-python PDF library. Prior to 6.12.0, an attacker who uses this vulnerability can craft a PDF which leads to large memory usage. This requires extracting text in layout mode with large character offsets. This vulnerability is fixed in 6.12.0.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - pypdf is a free and open-source pure-python PDF library. Prior to 6.12.0, an attacker who uses this
    vulnerability can craft a PDF which leads to large memory usage. This requires extracting text in layout
    mode with large character offsets. This vulnerability is fixed in 6.12.0. (CVE-2026-48155)

The version of IBM Cognos Analytics installed on the remote host is 12.1.x prior to 12.1.3 FP2. It is, therefore, affected by multiple vulnerabilities as referenced in the IBM Security Bulletin No. 7287209. These vulnerabilities are applicable only to version 12.1.3 due to newer functionalities and an updated software stack:

  - Arbitrary class instantiation via model manifest in Apache OpenNLP ExtensionLoader. The     ExtensionLoader.instantiateExtension() method loads a class by its fully-qualified name via     Class.forName() and invokes its no-arg constructor, with the class name sourced from the     manifest.properties entry of a model archive. An attacker who can supply a crafted model archive can     cause the static initializer of any class on the classpath to run during model loading.
    (CVE-2026-42027)

  - XML External Entity (XXE) via unsanitized dictionary parsing in Apache OpenNLP     DictionaryEntryPersistor. An attacker who can supply a crafted dictionary file containing a malicious     DOCTYPE declaration can trigger local file disclosure via file:// entity references or server-side     request forgery via http:// entity references during SAX parsing. (CVE-2026-40682)

  - An authenticated attacker may bypass the fix in CVE-2026-34197 by adding a connector using an HTTP     Discovery transport via BrokerView.addNetworkConnector or BrokerView.addConnector through Jolokia if the     activemq-http module is on the classpath, resulting in arbitrary code execution on the Apache ActiveMQ     broker's JVM. (CVE-2026-40466)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

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 6.12.0, an attacker who uses this     vulnerability can craft a PDF which leads to large memory usage. This requires extracting text in layout     mode with large character offsets. This vulnerability is fixed in 6.12.0. (CVE-2026-48155)

Note that Nessus relies on the presence of the package as reported by the vendor.
