CVE-2010-1919
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 · uneditedUnspecified vulnerability in EMC Avamar 4.1.x and 5.0 before SP1 allows remote attackers to cause a denial of service (gsan service hang) by sending a crafted message using TCP.
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 confidenceEMC Avamar versions 4.1.x and 5.0 before SP1 contain an unspecified vulnerability in the gsan service that allows remote attackers to cause a denial of service by sending a crafted TCP message, resulting in service hang.

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.
-
Identify if EMC Avamar is installedCheck for EMC Avamar installation directories or running processes related to Avamar. Look for process names like 'gsan' or check for Avamar installation under /opt/emc/avamar or similar paths.Affected if EMC Avamar software is found on the system
-
Determine the installed Avamar versionLocate the version file or use version checking commands specific to EMC Avamar. Common locations include /opt/emc/avamar/bin/avamar-version or similar version files within the installation directory.Affected if The version cannot be determined or is not visible
-
Compare version against affected rangesCompare the installed version to the affected ranges: 4.1.x (all versions) and 5.0 before SP1. Determine if the version falls within CVE-2010-1919's affected scope.Affected if Version is 4.1.x or 5.0 (any subversion before SP1)
-
Check if gsan service is runningVerify the gsan service status. This may involve checking running processes for 'gsan' or using service management commands specific to Avamar.Affected if The gsan service is actively running on the system
-
Inspect for service degradation symptomsReview system logs, Avamar service logs, and check for gsan service hang or unresponsive state. Look for sudden service interruptions or TCP-related errors.Affected if The gsan service is hung, unresponsive, or has recently crashed
A user is affected if they have EMC Avamar version 4.1.x or 5.0 before SP1 installed with the gsan service enabled and running, as the vulnerability resides specifically in that service component.
