Linux ≫ Linux Kernel

The System V (SYS5) shared memory implementation for Linux kernel before 2.2.19 could allow attackers to modify recently freed memory.

Masquerading code for Linux kernel before 2.2.19 does not fully check packet lengths in certain cases, which may lead to a vulnerability.

Certain operations in Linux kernel before 2.2.19 on the x86 architecture copy the wrong number of bytes, which might allow attackers to modify memory, aka "User access asm bug on x86."

Unknown vulnerabilities in the UDP port allocation for Linux kernel before 2.2.19 could allow local users to cause a denial of service (deadlock).

The "mxcsr P4" vulnerability in the Linux kernel before 2.2.17-14, when running on certain Intel CPUs, allows local users to cause a denial of service (system halt).

The "capabilities" feature in Linux before 2.2.16 allows local users to cause a denial of service or gain privileges by setting the capabilities to prevent a setuid program from dropping privileges, aka the "Linux kernel setuid/setcap vulnerability."

A system does not present an appropriate legal message or warning to a user who is accessing it.

The knfsd NFS server in Linux kernel 2.2.x allows remote attackers to cause a denial of service via a negative size value.

IP masquerading in Linux 2.2.x allows remote attackers to route UDP packets through the internal interface by modifying the external source IP address and port number to match those of an established connection.

The Linux 2.2.x kernel does not restrict the number of Unix domain sockets as defined by the wmem_max parameter, which allows local users to cause a denial of service by requesting a large number of sockets.
