CVE-2025-26310

6.5 MEDIUM

📋 TL;DR

Multiple memory leaks in ABC file parsing functions in libming v0.4.8 allow attackers to cause denial of service through crafted ABC files. This affects applications that process ABC files using vulnerable libming versions, potentially leading to resource exhaustion.

💻 Affected Systems

Products:
  • libming
Versions: v0.4.8 and possibly earlier versions
Operating Systems: All platforms running libming
Default Config Vulnerable: ⚠️ Yes
Notes: Any application using libming's ABC file parsing functions is vulnerable when processing untrusted ABC files.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete service unavailability due to memory exhaustion, potentially affecting multiple services if libming is used in shared environments.

🟠

Likely Case

Degraded performance or crashes of applications processing malicious ABC files, requiring service restarts.

🟢

If Mitigated

Minimal impact with proper input validation and resource limits in place.

🌐 Internet-Facing: MEDIUM - Requires processing of attacker-controlled ABC files, which may occur in web applications or file upload services.
🏢 Internal Only: LOW - Requires internal users to process malicious files, less likely in controlled environments.

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ⚠️ Yes
Complexity: LOW

Exploitation requires the ability to supply crafted ABC files to vulnerable parsing functions.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Check GitHub issue #328 for latest patched version

Vendor Advisory: https://github.com/libming/libming/issues/328

Restart Required: Yes

Instructions:

1. Monitor libming GitHub repository for patches
2. Apply patches to libming source code
3. Recompile and reinstall libming
4. Restart affected applications

🔧 Temporary Workarounds

Input Validation

all

Implement strict validation of ABC files before processing

Resource Limits

linux

Set memory limits on processes using libming ABC parsing

ulimit -v [LIMIT] # Linux memory limit

🧯 If You Can't Patch

  • Implement network segmentation to isolate systems using libming
  • Monitor for abnormal memory usage patterns in applications processing ABC files

🔍 How to Verify

Check if Vulnerable:

Check libming version and verify if ABC parsing functions are used in your application

Check Version:

ming-config --version or check library files

Verify Fix Applied:

Test with known malicious ABC files after patching to ensure no memory leaks occur

📡 Detection & Monitoring

Log Indicators:

  • Abnormal memory usage patterns
  • Application crashes when processing ABC files
  • Repeated process restarts

Network Indicators:

  • Unusual ABC file uploads to services
  • Multiple large ABC file processing requests

SIEM Query:

Process memory usage > threshold AND process name contains libming-related terms
