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.
