Summary

In MongoDB libbson 1.7.0, the bson_iter_codewscope function in bson-iter.c miscalculates a bson_utf8_validate length argument, which allows remote attackers to cause a denial of service (heap-based buffer over-read in the bson_utf8_validate function in bson-utf8.c), as demonstrated by bson-to-json.c.

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Overread Buffers
    An adversary attacks a target by providing input that causes an application to read beyond the boundary of a defined buffer. This typically occurs when a value influencing where to start or stop reading is set to reflect positions outside of the valid memory location of the buffer. This type of attack may result in exposure of sensitive information, a system crash, or arbitrary code execution.
