CVE-2023-22652
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') vulnerability in openSUSE libeconf leads to DoS via malformed config files. This issue affects libeconf: before 0.5.2.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidencelibeconf (a library for handling configuration files in openSUSE) contains a classic buffer overflow vulnerability where the library copies data into a fixed-size buffer without validating the input size. When parsing malformed config files, this can cause the buffer to overflow, leading to denial of service.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Determine installed libeconf versionRun 'rpm -q libeconf' or 'rpm -qa | grep libeconf' to query the installed package versionAffected if The reported version is lower than 0.5.2 (e.g., 0.5.1, 0.5.0, or earlier)
-
Verify libeconf library is presentCheck for the library file: 'ls -la /usr/lib*/libeconf.so*' or 'ldconfig -p | grep econf'Affected if The library exists and its version cannot be determined or is below 0.5.2
-
Identify applications using libeconfRun 'ldd /usr/bin/* 2>/dev/null | grep econf' or check package dependencies for packages that depend on libeconfAffected if Any application dynamically links to libeconf and the library version is vulnerable
-
Check if config file parsing occursReview application logs or monitor for config file loading operations (look for .conf, .ini, or settings files being read by linked applications)Affected if Applications linked to libeconf process configuration files and the library version is below 0.5.2
You are affected if libeconf version 0.5.2 or higher is not installed and any application on the system uses libeconf to parse configuration files.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped0.5.2
Upgrade libeconf to version 0.5.2 or later to obtain the patched version that properly validates input sizes before buffer copy operations.
libeconf 0.5.2 or later
- 1. Identify the current installed version of libeconf on the system using package manager (e.g., `dpkg -l libeconf` or `rpm -q libeconf` or equivalent)
- 2. Update the package repository to ensure latest packages are available
- 3. Upgrade libeconf to version 0.5.2 or later using the system's package manager (e.g., `zypper update libeconf`, `dnf update libeconf`, or `apt-get install libeconf`)
- 4. Verify the upgraded version meets the fix requirement (>= 0.5.2)
- 5. Test that affected applications using libeconf function correctly with the updated library
