CVE-2007-5378: Buffer overflow in the FileReadGIF function in tkImgGIF.c for Tk Toolkit 8.4.12 and earlier, and 8.3.5 and...

Buffer overflow in the FileReadGIF function in tkImgGIF.c for Tk Toolkit 8.4.12 and earlier, and 8.3.5 and earlier, allows user-assisted attackers to cause a denial of service (segmentation fault) via an animated GIF in which the first subimage is smaller than a subsequent subimage, which triggers the overflow in the ReadImage function, a different vulnerability than CVE-2007-5137.

Security readout for executives and security teams

This is an old Tk Toolkit GIF parsing flaw. A specially crafted animated GIF can crash software that uses vulnerable Tk image handling. The available sources describe denial of service, not confirmed code execution or active exploitation. Exposure is most likely in legacy systems, packaged applications, or vendor products embedding old Tk versions and processing user-supplied GIF images. Modern systems are less likely affected if vendor Tk packages were updated after the referenced 2007-2009 advisories. Treat this as a legacy exposure cleanup item unless vulnerable Tk is reachable through business workflows that process untrusted images. Prioritize internet-facing, helpdesk, document-preview, or user-content environments first. Mitigation focus: Inventory systems using Tk 8.4.12 or earlier, or 8.3.5 or earlier.; Apply applicable vendor updates from OS or product advisories.; Restrict processing of untrusted GIF files in vulnerable legacy applications..
