FreeBSD : libxml2 stack buffer overflow in URI parsing (847ade05-6717-11d8-b321-000a95bc6fae)

High Nessus Plugin ID 36421


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


Yuuichi Teranishi reported a crash in libxml2's URI handling when a long URL is supplied. The implementation in nanohttp.c and nanoftp.c uses a 4K stack buffer, and longer URLs will overwrite the stack. This could result in denial-of-service or arbitrary code execution in applications using libxml2 to parse documents.


Update the affected package.
