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
Buffer overflow in url.c in MPlayer 1.0rc2 and SVN before r25823 allows remote attackers to execute arbitrary code via a crafted URL that prevents the IPv6 parsing code from setting a pointer to NULL, which causes the buffer to be reused by the unescape code.

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 overflow in MPlayer's url.c file where IPv6 parsing code fails to set a pointer to NULL, causing the buffer to be improperly reused by the unescape code. This allows remote attackers to execute arbitrary code via crafted URLs that trigger the condition.

MitigationUpgrade to MPlayer SVN r25823 or later, or apply the patch that ensures proper NULL pointer initialization in the IPv6 parsing code before buffer reuse.

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. Check installed MPlayer version
    Run 'mplayer -version' or 'mplayer -v' to display version information
    Affected if Version displayed is exactly 1.02rc2
  2. Identify the vulnerable binary location
    Locate the mplayer executable using 'which mplayer' or 'where mplayer' on Windows
    Affected if The binary exists and was built from the 1.02rc2 source code
  3. Verify the vulnerable url.c is in use
    Check if the binary links against libavformat or contains the url.c parsing logic by running 'ldd mplayer' or examining the binary with 'strings' for 'ipv6' related strings
    Affected if The binary contains IPv6 URL parsing code from the affected source version
  4. Confirm URL handling is accessible
    Test that MPlayer can accept URLs as input by attempting to play a media file via URL: 'mplayer http://example.com/test.mp3'
    Affected if URL input feature is enabled and functional, allowing crafted URLs to be processed

A system is affected if MPlayer version 1.02rc2 is installed and the IPv6 URL parsing functionality is accessible, as the buffer overflow occurs when processing specially crafted URLs through the vulnerable url.c code.
