CVE-2026-1767
Description
A flaw was found in the GNOME localsearch (previously known as tracker-miners) MP3 Extractor tracker-extract-mp3 component. A remote attacker could exploit this heap buffer overflow vulnerability by providing a specially crafted MP3 file containing malformed ID3 tags. This incorrect length calculation during the parsing of performer tags can lead to a read beyond the allocated buffer, potentially causing a Denial of Service (DoS) due to a crash or enabling information disclosure.
Statement
This vulnerability has MODERATE impact. A heap buffer overflow in the GNOME localsearch MP3 Extractor (tracker-extract-mp3). A specially crafted MP3 file with malformed ID3 tags can cause the tracker-extract process to read beyond its allocated buffer. This can lead to a denial of service through application crashes or potentially information disclosure. This vulnerability requires local processing of a malicious MP3 file.
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.

Understanding the Weakness (CWE)
Integrity,Confidentiality,Availability
Technical Impact: Read Memory; Modify Memory; Execute Unauthorized Code or Commands
Buffer overflows often can be used to execute arbitrary code, which is usually outside the scope of a program's implicit security policy. This can often be used to subvert any other security service.
Availability
Technical Impact: Modify Memory; DoS: Crash, Exit, or Restart; DoS: Resource Consumption (CPU)
Buffer overflows generally lead to crashes. Other attacks leading to lack of availability are possible, including putting the program into an infinite loop.
