Honeyd test.sh symlink
| honeyd-test-symlink (44735) |  Medium Risk |
Description:
Honeyd could allow a local attacker to launch a symlink attack, caused by an error in the test.sh script. Temporary files are created with insecure permissions. A local attacker could exploit this vulnerability by creating a symbolic link from a temporary file to other files on the system, which would allow the attacker to overwrite arbitrary files on the system with elevated privileges.
