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 · unedited
Heap-based buffer overflow in the ne_rfc1036_parse date parsing function for the neon library (libneon) 0.24.5 and earlier, as used by cadaver before 0.22, allows remote WebDAV servers to execute arbitrary code on the client.

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 · high confidence

Heap-based buffer overflow in the ne_rfc1036_parse date parsing function of libneon 0.24.5 and earlier allows a malicious WebDAV server to send specially crafted date responses that overflow the heap buffer, enabling arbitrary code execution on the connected client.

MitigationUpgrade libneon to version 0.24.6 or later, and upgrade cadaver to version 0.22 or later, to obtain the patched date parsing function.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify installed libneon version
    Run `dpkg -l libneon25` or `neon-config --version` to find the installed libneon library version
    Affected if Version is 0.24.5 or earlier
  2. Identify installed cadaver version
    Run `cadaver --version` or check package version via `dpkg -l cadaver`
    Affected if Version is less than 0.22.0
  3. Check for neon library files
    Locate libneon shared libraries with `find /usr -name 'libneon*' 2>/dev/null` and note the file name which may contain the version
    Affected if Found library file corresponds to version 0.24.5 or earlier
  4. Verify date parsing is used
    Inspect which applications link against libneon using `ldd $(which <webdav-client>) 2>/dev/null | grep neon` or check application dependencies
    Affected if Client application uses libneon for WebDAV connections and libneon version is vulnerable

A user is affected if they have libneon version 0.24.5 or earlier or cadaver version below 0.22.0 installed and use these vulnerable components to connect to WebDAV servers.

Upgrade available Upgrade to 0.22.0 or later
Fixed in 0.22.0
Interim mitigation

Upgrade libneon to version 0.24.6 or later, and upgrade cadaver to version 0.22 or later, to obtain the patched date parsing function.
