Design/Logic Flaw

In Yubico pam-u2f 1.0.7, when configured with debug and a custom debug log file is set using debugfile, that file descriptor is not closed when a new process is spawned. This leads to the file descriptor being inherited into the child process; the child process can then read from and write to it...

UBUNTU-CVE-2016-6831

The "process-execute" and "process-spawn" procedures did not free memory correctly when the execve call failed, resulting in a memory leak. This could be abused by an attacker to cause resource exhaustion or a denial of service. This affects all releases of CHICKEN up to and including 4.11 it wil...

CVE-2016-6830

The "process-execute" and "process-spawn" procedures in CHICKEN Scheme used fixed-size buffers for holding the arguments and environment variables to use in its execve call. This would allow user-supplied argument/environment variable lists to trigger a buffer overrun. This affects all releases o...
