Who should care

Defenders responsible for Ghidra installations should assess exposure and prioritize verifying installations to prevent potential Denial of Service attacks via compressed theme archives.

Why it matters

Defenders should prioritize verifying Ghidra installations and assessing exposure to potential Denial of Service attacks via compressed theme archives. The vulnerability in Ghidra 10.3 before 12.2 could lead to data loss or corruption, and attackers may persuade users to import malicious theme ZIP files. Verification of installations and implementation of measures to prevent malicious imports are crucial.

  • Potential Denial of Service due to improper handling of highly compressed data in theme archives.
  • Possible data loss or corruption due to failed writes on the host filesystem.
  • Need for verification of Ghidra installations to ensure they are up-to-date with the latest security patches.
  • Potential for attackers to persuade users to import malicious theme ZIP files.

Technical summary

Ghidra 10.3 before 12.2 contains an improper handling of highly compressed data vulnerability in ThemeReader.processIconFile() that fails to limit decompressed size or compression ratio. Attackers can persuade a user to import a crafted theme ZIP whose icon entries expand to fill the host filesystem, causing later writes to fail. The vulnerability could lead to a Denial of Service via compressed theme archives, and defenders should prioritize verifying Ghidra installations and assessing exposure to potential attacks. The CVE record and source item provide details on the vulnerability, but specific details on exploitation and impact are limited.

Defensive priority

Defenders should prioritize verifying Ghidra installations and assessing exposure to potential Denial of Service attacks via compressed theme archives.

Recommended defensive actions

  • Verify Ghidra installations to ensure they are up-to-date with the latest security patches.
  • Assess exposure to potential Denial of Service attacks via compressed theme archives.
  • Implement measures to prevent the import of malicious theme ZIP files.
  • Review compensating controls for exposed systems while remediation is scheduled and verified.
  • Check relevant monitoring, detection, and logs for exposed assets that need extra review.
  • Track exceptions, retest remediated assets, and close the item only after evidence is documented.
  • Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up.

Evidence notes

The CVE record and source item provide details on the vulnerability in Ghidra 10.3 before 12.2, which could lead to a Denial of Service via compressed theme archives. However, specific details on exploitation and impact are limited.
