The transform_save function in transform.c in Augeas before 1.0.0 allows local users to overwrite arbitrary files and obtain sensitive information via a symlink attack on a .augsave file in a backup save action, a different vector than CVE-2012-0786.

The transform_save function in transform.c in Augeas 1.0.0 through 1.1.0 does not properly calculate the permission values when the umask contains a "7," which causes world-writable permissions to be used for new files and allows local users to modify the files via unspecified vectors.

Augeas versions up to and including 1.8.0 are vulnerable to heap-based buffer overflow due to improper handling of escaped strings. Attacker could send crafted strings that would cause the application using augeas to copy past the end of a buffer, leading to a crash or possible code execution.
