Gnu · Gnu Libredwg · CVE-2018-14471
**Name of the Vulnerable Software and Affected Versions**
GNU LibreDWG version 0.5.1048
**Description**
The issue allows remote attackers to cause a denial of service, resulting in a NULL pointer dereference and SEGV, via a crafted dwg file. This is due to a problem in the `dwg obj block control get block headers` function in `dwg api.c`.
**Recommendations**
For GNU LibreDWG version 0.5.1048, as a temporary workaround, consider restricting the use of the `dwg obj block control get block headers` function until a patch is available. Avoid using this function with untrusted dwg files to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this issue.
