            Bug ID: 29363
           Summary: Some memory leaks occur when binutils code is tested
                    using the binutils fuzz test suite.
           Product: binutils
           Version: 2.37
            Status: UNCONFIRMED
          Severity: critical
          Priority: P2
         Component: gas
          Assignee: unassigned at sourceware dot org
          Reporter: shenxiaogll at 163 dot com
  Target Milestone: ---

OS:Linux
Arch:X86_64
The binutils fuzz test code：
https://github.com/google/oss-fuzz/tree/master/projects/binutils

Memory leakage occurs in the following cases:
fuzz_as

fuzz_as:
In the as.c logic implementation of the source code of the /usr/bin/as tool,
the *_begin() and *_init() initialization functions are invoked to allocate
memory space. The memory is used in subsequent logic processing. However, some
initialization functions (memory has been allocated) do not provide the
corresponding memory release function. The involved code logic is too complex
and requires further attention.
Many release operations in the binutils source code depend on automatic release
upon process exit. The memory allocation operation does not provide the
corresponding memory release interface.

Leaked Memory:
++ tail -300 fuzz_as-address.log
