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
Multiple buffer overflows in the voicemail functionality in Asterisk 1.4.x before 1.4.13, when using IMAP storage, might allow (1) remote attackers to execute arbitrary code via a long combination of Content-type and Content-description headers, or (2) local users to execute arbitrary code via a long combination of astspooldir, voicemail context, and voicemail mailbox fields. NOTE: vector 2 requires write access to Asterisk configuration files.

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

Buffer overflows in Asterisk 1.4.x voicemail functionality when using IMAP storage allow remote attackers to execute arbitrary code via specially crafted Content-type and Content-description headers, or local users with write access to Asterisk configuration files to execute code via long astspooldir, voicemail context, and voicemail mailbox fields.

MitigationUpgrade Asterisk to version 1.4.13 or later which contains the patched bounds checking for the IMAP voicemail storage functionality; if immediate upgrade is not feasible, disable IMAP voicemail storage and restrict access to Asterisk configuration files.

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 Asterisk version
    Run 'asterisk -V' or 'asterisk -x "core show version"' to determine the installed version of Asterisk
    Affected if The installed version is 1.4.12 or earlier
  2. Verify IMAP voicemail storage is in use
    Examine /etc/asterisk/imap.conf or run 'asterisk -x " voicemail show settings"' to check if IMAP storage is configured for voicemail
    Affected if IMAP storage is enabled in the voicemail configuration
  3. Inspect voicemail configuration files for long field values
    Review /etc/asterisk/voicemail.conf and look for the 'astspooldir', 'context', and 'mailbox' settings; check if any contain unusually long string values that could indicate exploitation
    Affected if Configuration files contain long values in astspooldir, voicemail context, or mailbox fields, or are writable by untrusted users
  4. Check file permissions on Asterisk configuration directory
    Run 'ls -la /etc/asterisk/' and verify that configuration files are not world-writable or group-writable by unauthorized users
    Affected if Asterisk configuration files are writable by users other than root/asterisk

You are affected if running Asterisk version 1.4.12 or earlier with IMAP voicemail storage enabled, or if Asterisk configuration files are writable by untrusted local users.

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 data
Upgrade available Upgrade to a release after 1.4.12
Interim mitigation

Upgrade Asterisk to version 1.4.13 or later which contains the patched bounds checking for the IMAP voicemail storage functionality; if immediate upgrade is not feasible, disable IMAP voicemail storage and restrict access to Asterisk configuration files.
