Who should care

Defenders responsible for systems that use libtta, particularly those using 32-bit builds, should assess their exposure and take steps to verify and mitigate the vulnerability. This includes verifying the version of libtta used, applying patches or updates if available, and implementing measures to validate and sanitize input files.

Why it matters

CVE-2026-112011 is a medium-severity integer overflow vulnerability in libtta through 2.3 that allows attackers to cause a heap buffer overflow on 32-bit builds. Defenders should prioritize verifying the version of libtta used in their systems and applying patches or updates if available.

• Verify the version of libtta used in your systems and apply patches or updates if available.
• Implement measures to validate and sanitize input files to prevent exploitation.
• Monitor systems for potential exploitation attempts.

Technical summary

The tta_decoder_init_get_info() function in libtta through 2.3 contains an integer overflow vulnerability. This vulnerability allows attackers to cause a heap buffer overflow on 32-bit builds via unvalidated header fields in a crafted .tta file with a sample rate of 1 and large samples value, wrapping the seek table allocation and crashing applications. The vulnerability is considered medium severity with a CVSS score of 5.8. Defenders should prioritize verifying the version of libtta used in their systems and applying patches or updates if available. They should also implement measures to validate and sanitize input files to prevent exploitation, and review compensating controls for exposed systems.

Defensive priority

Defenders should prioritize verifying the version of libtta used in their systems and applying patches or updates if available. They should also implement measures to validate and sanitize input files to prevent exploitation.

Recommended defensive actions

• Verify the version of libtta used in your systems and apply patches or updates if available.
• Implement measures to validate and sanitize input files to prevent exploitation.
• Monitor systems for potential exploitation attempts.
• 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.
