AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability exists in the Binutils objdump tool, specifically when it processes a crafted binary containing malformed DWARF debug information.
A logic error in how DWARF compilation units are handled causes an invalid offset_size value to be used inside the function byte_get_little_endian, which leads to the program aborting unexpectedly (SIGABRT).
This issue was observed in binutils version 2.44 and can be triggered locally by an attacker providing a malicious input file.
How can this vulnerability impact me? :
The vulnerability can cause a denial-of-service condition by crashing the objdump tool when it processes a maliciously crafted binary file.
A local attacker can exploit this by supplying a specially crafted input file that triggers the crash, potentially disrupting workflows or automated processes that rely on objdump.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
