CVE-2017-9053
CriticalSummary
An issue was discovered in libdwarf related to a heap-based buffer over-read in the _dwarf_read_loc_expr_op() function. This problem is due to a failure to check if a pointer is within bounds.
Risk Assessment
The buffer over-read may lead to the disclosure of sensitive information or application instability, posing a security threat to the system.
Recommendation
It is recommended to update the libdwarf library to the latest version to mitigate this vulnerability and implement additional pointer checks in the code.
