A flaw was found in parted. A heap-based buffer overflow can occur when processing a specially crafted FAT32 filesystem due to an integer calculation error during buffer allocation. A local attacker could exploit this by enticing a user or automated service to open a malicious filesystem image, resulting in an application crash leading to a Denial of Service (DoS) or potential memory corruption.

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

  - A flaw was found in parted. A heap-based buffer overflow can occur when processing a specially crafted
    FAT32 filesystem due to an integer calculation error during buffer allocation. A local attacker could
    exploit this by enticing a user or automated service to open a malicious filesystem image, resulting in an
    application crash leading to a Denial of Service (DoS) or potential memory corruption. (CVE-2026-89085)

The remote CentOS Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the parted-3.5-4.el9 build changelog.

  - CVE-2026-89088 (CVE-2026-89085)

  - A flaw was found in parted. A heap-based buffer overflow exists in libparted's file system resizing logic     when handling FAT16 volumes. By convincing a user or administrator to resize a specially crafted FAT16     file system image with malformed directory metadata, an attacker can trigger an oversized read into a     fixed-size memory buffer. This issue causes memory corruption, resulting in an application crash and a     denial of service (DoS). (CVE-2026-89088)

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

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-3189 advisory.
