Sun Solaris rm command denial of service
| solaris-rm-dos (32399) |  Medium Risk |
Description:
Sun Solaris is vulnerable to a denial of service, caused by a race condition in the -r and -R options of the rm command when deleting recursive directories. By creating a specially-crafted directory hierarchy, a local attacker could delete arbitrary files on the system, if the attacker could persude the victim to delete the malicious directory hierarchy using the rm command.

- CVE-2007-0895: Race condition in recursive directory deletion with the (1) -r or (2) -R option in rm in Solaris 8 through 10 before 20070208 allows local users to delete files and directories as the user running rm by moving a low-level directory to a higher level as it is being deleted, which causes rm to chdir to a .. directory that is higher than expected, possibly up to the root file system, a related issue to CVE-2002-0435.
