It was reported [1] that ibutils 1.5.7 suffered from a flaw due to improper handling of files in the /tmp directory. This makes ibutils vulnerable to symlink attacks, which could be used to overwrite arbitrary files on the system.
[1] http://seclists.org/fulldisclosure/2013/Mar/87
ibutils packages as shipped in Red Hat Enterprise Linux 4 and 5 are built to use insecure RPATH set in the ELF header of the ibmssh command.
This issue can possibly be exploited by a local attacker to run arbitrary code as some other user if victim user can be convinced to run ibmssh command in an attacker controlled directory with specially crafted content.
Affected binary: /usr/bin/ibmssh RPATH: refix/lib
