Atril Document Viewer is the default document reader of the MATE desktop environment for Linux. A path traversal and arbitrary file write vulnerability exists in versions of Atril prior to 1.26.2. This vulnerability is capable of writing arbitrary files anywhere on the filesystem to which the user opening a crafted document has access. The only limitation is that this vulnerability cannot be exploited to overwrite existing files, but that doesn't stop an attacker from achieving Remote Command Execution on the target system. Version 1.26.2 of Atril contains a patch for this vulnerability.

The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-3828 advisory.

    Package        : atril     Version        : 1.20.3-1+deb10u2     CVE ID         : CVE-2023-52076     Debian Bug     : 1061522

    A vulnerability was discovered in Atril, a simple document viewer designed for     the MATE desktop environment.

    CVE-2023-52076

      A missing input sanitising could result in writing arbitrary files if a       malformed epub document is opened, that could result in arbitrary code       execution.

    For Debian 10 buster, these problems have been fixed in version     1.20.3-1+deb10u2. This update also disables support for comic book archives,     mitigating CVE-2023-51698.

    We recommend that you upgrade your atril packages.
