gdb vulnerability

A security issue affects these releases of Ubuntu and its derivatives:

  • Ubuntu 6.06 LTS

  • Ubuntu 5.04

Software Description


Will Drewry, of the Google Security Team, discovered buffer overflows in GDB’s DWARF processing. This would allow an attacker to execute arbitrary code with user privileges by tricking the user into using GDB to load an executable that contained malicious debugging information.
