CVE-2008-5237
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 · uneditedMultiple integer overflows in xine-lib 1.1.12, and other 1.1.15 and earlier versions, allow remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via (1) crafted width and height values that are not validated by the mymng_process_header function in demux_mng.c before use in an allocation calculation or (2) crafted current_atom_size and string_size values processed by the parse_reference_atom function in demux_qt.c for an RDRF_ATOM string.
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 confidenceInteger overflows in xine-lib's MNG and QuickTime demuxers allow attackers to trigger heap corruption via crafted width/height values (demux_mng.c mymng_process_header) or atom/string_size values (demux_qt.c parse_reference_atom) that bypass allocation-size validation, potentially enabling arbitrary code execution.

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 installed xine-lib versionRun `xine-config --version` or check the shared library file (e.g., libxine.so.1) using `ldd --version` or inspect the file metadataAffected if The reported version matches any of these: 0.9.13, 1.0, 1.0.1, 1.0.2, 1.0.3a, 1.1.0, 1.1.1, 1.1.2, 1.1.3, 1.1.4, or any version 1.1.5 or lower
-
Confirm MNG demuxer is availableCheck for the presence of demux_mng.c source file or MNG plugin module in the xine-lib plugins directory (commonly /usr/lib/xine/plugins or similar)Affected if The MNG demuxer plugin is present and loaded by xine when processing MNG media files
-
Confirm QuickTime demuxer is availableCheck for the presence of demux_qt.c source file or QuickTime plugin module in the xine-lib plugins directoryAffected if The QuickTime demuxer plugin is present and loaded by xine when processing QuickTime media files
-
Verify vulnerable code path existsInspect the xine-lib source code for functions mymng_process_header in demux_mng.c and parse_reference_atom in demux_qt.c; look for memory allocation calls using width, height, current_atom_size, or string_size without proper bounds checkingAffected if These functions exist and the allocation-size validation can be bypassed by malicious width/height or atom/string_size values in crafted media files
You are affected if xine-lib version 1.1.5 or lower is installed AND the MNG or QuickTime demuxer modules are available to process media files.

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.
dbcve · scopedUpgrade xine-lib to version 1.1.16 or later; alternatively, implement bounds validation on width, height, current_atom_size, and string_size values before use in memory allocation calculations in the affected demuxer functions.
xine-lib 1.1.16 or later (or latest stable 1.x release)
- 1. Identify the exact xine-lib version currently installed in your system
- 2. If running xine-lib <= 1.1.15, upgrade to version 1.1.16 or later
- 3. Rebuild any applications that link against xine-lib after upgrading
- 4. Verify the upgrade by checking that the mymng_process_header function in demux_mng.c now properly validates width and height values before allocation calculations
- 5. Confirm parse_reference_atom function in demux_qt.c now validates current_atom_size and string_size values before use
