CVE-2001-0554debiandebian_linux+10
EPSS score38.75%
Buffer overflow in BSD-based telnetd telnet daemon on various operating systems allows remote attackers to execute arbitrary commands via a set of options including AYT (Are You There), which is not properly handled by the telrcv function.CVE-2005-0178linuxlinux_kernel+2EPSS score0.36%
Race condition in the setsid function in Linux before 2.6.8.1 allows local users to cause a denial of service (crash) and possibly access portions of kernel memory, related to TTY changes, locking, and semaphores.CVE-2004-0640debiannetkit-telnet-ssl+2EPSS score4.49%
Format string vulnerability in the SSL_set_verify function in telnetd.c for SSLtelnet daemon (SSLtelnetd) 0.13 allows remote attackers to execute arbitrary code.CVE-2019-7282debiannetkit-rsh+4EPSS score2.07%
In NetKit through 0.17, rcp.c in the rcp client allows remote rsh servers to bypass intended access restrictions via the filename of . or an empty filename. The impact is modifying the permissions of the target directory on the client side. This is similar to CVE-2018-20685.CVE-2019-7283debiannetkit-rsh+3EPSS score1.76%
An issue was discovered in rcp in NetKit through 0.17. For an rcp operation, the server chooses which files/directories are sent to the client. However, the rcp client only performs cursory validation of the object name returned. A malicious rsh server (or Man-in-The-Middle attacker) can overwrite arbitrary files in a directory on the rcp client machine. This is similar to CVE-2019-6111.CVE-2023-38336debiannetkit-rsh+2EPSS score2.06%
netkit-rcp in rsh-client 0.17-24 allows command injection via filenames because /bin/sh is used by susystem, a related issue to CVE-2006-0225, CVE-2019-7283, and CVE-2020-15778.CVE-2006-6008debianlinux-ftpd+1EPSS score2.06%
ftpd in Linux Netkit (linux-ftpd) 0.17, and possibly other versions, does not check the return status of certain seteuid, setgid, and setuid calls, which might allow remote authenticated users to gain privileges if these calls fail in cases such as PAM failures or resource limits, a different vulnerability than CVE-2006-5778.
