CVE-1999-1048

Summary

CVE-1999-1048 is a buffer overflow vulnerability affecting older versions of the Bash shell (2.0.0 and 1.4.17). An attacker can exploit this flaw by crafting an excessively long directory name and inserting it into the PS1 environmental variable via the '\w' option. When another user navigates to that directory, the Bash interpreter encounters a buffer overflow, enabling the attacker to gain elevated privileges locally.
