Solaris is the variant of the UNIX Operating System distributed by Sun Microsystems. Solaris is designed as a scalable operating system for the Intel x86 and Sun Sparc platforms, and operates on machines varying from desktop to enterprise server.

A problem with the handling of a long string of characters by the -F option makes it possible for a local user to gain elevated privileges. Due to the insufficient handling of input by the -F option of mailx, a buffer overflow at 1150 characters makes it possible to overwrite variables on the stack, including the return address.

This problem makes it possible for a local user gain elevated privileges, attaining an effective GID of mail.
