FreeBSD : curl -- libcurl buffer overflow vulnerability (c8c31c41-49ed-11df-83fb-0015587e2cc1)

Medium Nessus Plugin ID 45574


The remote FreeBSD host is missing a security-related update.


The cURL project reports in a security advisory :

Using the affected libcurl version to download compressed content over HTTP, an application can ask libcurl to automatically uncompress data.
When doing so, libcurl can wrongly send data up to 64K in size to the callback which thus is much larger than the documented maximum size.

An application that blindly trusts libcurl's max limit for a fixed buffer size or similar is then a possible target for a buffer overflow vulnerability.


Update the affected package.
