CVE-2018-0510
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 · uneditedBuffer overflow in epg search result viewer (kkcald) 0.7.19 and earlier allows remote attackers to perform unintended operations or execute DoS (denial of service) attacks via unspecified vectors.
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 confidenceA buffer overflow vulnerability exists in the kkcald EPG (Electronic Program Guide) search result viewer version 0.7.19 and earlier. The flaw allows remote attackers to overflow a memory buffer, potentially enabling arbitrary code execution for unintended operations or causing a denial of service. The attack vector is network-accessible but the specific exploitation vectors are not detailed.

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.
-
Verify kkcald is installedCheck for the presence of kkcald binary or package: which kkcald, dpkg -l | grep kkcald, or rpm -qa | grep kkcaldAffected if kkcald is installed and running on the system
-
Determine installed versionRun kkcald --version or check package manager output (dpkg -l kkcald, rpm -qi kkcald)Affected if Version is 0.7.19 or lower, or if the version cannot be determined (older installation)
-
Check if EPG search service is exposedReview network configuration: netstat -anp | grep kkcald or ss -anp | grep kkcald to see listening ports; inspect /etc/kkcal/ or ~/.kkcal/ configuration files for network binding settingsAffected if kkcald is listening on a network-accessible interface (0.0.0.0 or external IP) rather than localhost only
-
Verify EPG search viewer is enabledCheck kkcald configuration files for EPG search result viewer module settings; look for keywords like 'epg', 'search', 'viewer', or 'enable' in config files within /etc/kkcal/ or ~/.kkcal/Affected if The EPG search result viewer module is enabled in configuration
Affected if kkcald version 0.7.19 or lower is installed with the EPG search result viewer enabled and network-accessible.

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.
From vendor dataUpgrade kkcald to a version beyond 0.7.19 (or the latest available version) to obtain the patched code. If upgrade is not immediately possible, restrict network access to the EPG service and implement input validation as a temporary defense.
