Jonathan Gray and Stanislaw Pitucha found an assertion failure in the way wrapped strings are parsed in Python-YAML, a YAML parser and emitter for Python

Summary

Jonathan Gray and Stanislaw Pitucha found an assertion failure in the
way wrapped strings are parsed in Python-YAML, a YAML parser and emitter
for Python. An attacker able to load specially crafted YAML input into an
application using python-yaml could cause the application to crash.

For the stable distribution (wheezy), this problem has been fixed in
version 3.10-4+deb7u1.

For the upcoming stable distribution (jessie), this problem has been
fixed in version 3.11-2.

For the unstable distribution (sid), this problem has been fixed in
