DESCRIPTION:
Two vulnerabilities have been reported in sblim-sfcb, which can be
exploited by malicious people to potentially compromise a vulnerable
system.

1) A vulnerability is caused due to the "getPayload()" function in
httpAdapter.c not properly verifying the size value provided via the
"Content-Length" header. This can be exploited to cause a heap-based
buffer overflow via specially crafted HTTP requests.

2) A vulnerability is caused due to a an integer overflow within the
"getPayload()" function in httpAdapter.c when receiving an overly
large size via the "Content-Length" header. This can be exploited to
cause a heap-based buffer overflow via specially crafted HTTP
requests.

Successful exploitation requires that the "httpMaxContentLength"
configuration setting is set to e.g. 0.

SOLUTION:
Update to version 1.3.8.

PROVIDED AND/OR DISCOVERED BY:
Reported by the vendor.
