CBL Mariner 2.0 Security Update: gdk-pixbuf2 (CVE-2025-6199)

low Nessus Plugin ID 242021

Synopsis

The remote CBL Mariner host is missing one or more security updates.

Description

The version of gdk-pixbuf2 installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2025-6199 advisory.

 - A flaw was found in the GIF parser of GdkPixbuf's LZW decoder. When an invalid symbol is encountered during decompression, the decoder sets the reported output size to the full buffer length rather than the actual number of written bytes. This logic error results in uninitialized sections of the buffer being included in the output, potentially leaking arbitrary memory contents in the processed image.
 (CVE-2025-6199)

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

Solution

Update the affected packages.
