CVE-2026-104067
Description
A flaw was found in Scribus. This vulnerability can lead to arbitrary code execution or a Denial of Service (DoS) due to an application crash. The StarView Metafile (SVM) import plugin fails to verify that bitmap and transparency mask dimensions match when processing files. An attacker could exploit this issue by convincing a user to open a specially crafted SVM file, triggering out-of-bounds memory reads and writes on the heap.
Statement
This vulnerability is rated as Important severity because successful exploitation can allow arbitrary code execution with the permissions of the logged-in user, though it requires explicit user interaction rather than enabling remote automated execution. In Red Hat environments, Scribus is not included in core Red Hat Enterprise Linux releases, significantly limiting exposure across enterprise server installations. The threat is primarily restricted to desktop environments where an operator manually imports or opens untrusted graphic files.
Mitigation
Upgrade to Scribus 1.6.7 or 1.7.4; avoid opening untrusted SVM files.
Understanding the Weakness (CWE)
Integrity
Technical Impact: Modify Memory; Execute Unauthorized Code or Commands
Write operations could cause memory corruption. In some cases, an adversary can modify control data such as return addresses in order to execute unexpected code.
Availability
Technical Impact: DoS: Crash, Exit, or Restart
Attempting to access out-of-range, invalid, or unauthorized memory could cause the product to crash.
Other
Technical Impact: Unexpected State
Subsequent write operations can produce undefined or unexpected results.
