Attackers can supply a crafted object file with a non-zero offset table, causing dwarf_debug_addr_by_index() to read past the heap buffer, disclosing adjacent heap bytes or crashing consumers.","cvssScore":4.4,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:L","cwes":["CWE-125"],"vendors":[],"products":[],"references":[{"url":"https://github.com/davea42/libdwarf-code","tags":[]},{"url":"https://github.com/davea42/libdwarf-code/blob/v2.3.3/src/lib/libdwarf/dwarf_debugaddr.c#L175-L216","tags":[]},{"url":"https://github.com/davea42/libdwarf-code/commit/71f04013ddc2a3c88b9e25a4162ee2824741b593","tags":[]},{"url":"https://github.com/davea42/libdwarf-code/issues/336","tags":[]},{"url":"https://hackmd.io/@haindpwn/libdwarf-debug-addr-table-section-offset-oob-read","tags":[]},{"url":"https://www.vulncheck.com/advisories/libdwarf-through-2.3.3-heap-out-of-bounds-read-via-dwarf-debug-addr-table","tags":[]}],"exploitRefs":[{"url":"https://github.com/davea42/libdwarf-code","tags":[]},{"url":"https://github.com/davea42/libdwarf-code/blob/v2.3.3/src/lib/libdwarf/dwarf_debugaddr.c#L175-L216","tags":[]},{"url":"https://github.com/davea42/libdwarf-code/commit/71f04013ddc2a3c88b9e25a4162ee2824741b593","tags":[]},{"url":"https://github.com/davea42/libdwarf-code/issues/336","tags":[]}],"hasPoc":true,"ai":null}
