Linux ≫ Linux Kernel

Linux kernel before 2.4.11pre3 in multiple Linux distributions allows local users to cause a denial of service (crash) by starting the core vmlinux kernel, possibly related to poor error checking during ELF loading.

Linux kernel 2.2.1 through 2.2.19, and 2.4.1 through 2.4.10, allows local users to cause a denial of service via a series of deeply nested symlinks, which causes the kernel to spend extra time when trying to access the link.

ptrace in Linux 2.2.x through 2.2.19, and 2.4.x through 2.4.9, allows local users to gain root privileges by running ptrace on a setuid or setgid program that itself calls an unprivileged program, such as newgrp.

IRC DCC helper in the ip_masq_irc IP masquerading module 2.2 allows remote attackers to bypass intended firewall restrictions by causing the target system to send a "DCC SEND" request to a malicious server which listens on port 6667, which may cause ...

Multiple TCP implementations could allow remote attackers to cause a denial of service (bandwidth and CPU exhaustion) by setting the maximum segment size (MSS) to a very small number and requesting large amounts of data, which generates more packets ...

ip_conntrack_ftp in the IPTables firewall for Linux 2.4 allows remote attackers to bypass access restrictions for an FTP server via a PORT command that lists an arbitrary IP address and port number, which is added to the RELATED table and allowed by ...

Linux kernel 2.4 and 2.2 allows local users to read kernel memory and possibly gain privileges via a negative argument to the sysctl call.

Race condition in ptrace in Linux kernel 2.4 and 2.2 allows local users to gain privileges by using ptrace to track and modify a running setuid process.

Unknown vulnerability in binfmt_misc in the Linux kernel before 2.2.19, related to user pages.

Off-by-one vulnerability in CPIA driver of Linux kernel before 2.2.19 allows users to modify kernel memory.
