Title
Gdb: gdb: stack buffer overflow in parse_tsv_definition via stale rs->buf tail
Summary
A flaw was found in the GNU debugger (GDB). When GDB connects to a remote debug target, a malicious target can cause GDB to overflow a buffer on the stack while parsing the target's replies. This can crash GDB or potentially allow the target to execute arbitrary code in the GDB client process with the privileges of the user running GDB.
Severity
No CVSS data available.
CWE
- CWE-121 - Stack-based Buffer Overflow
