Discussion

Linux Kernel Multiple Local Vulnerabilities

The Linux kernel is reported prone to multiple local vulnerabilities. The following individual issues are reported:

- An integer overflow is reported to exist in 'ip_options_get()' of the 'ip_options.c' kernel source file. This vulnerability is reported to exist only in the 2.6 kernel tree. Although unconfirmed, due to its nature this issue presumably may be further leveraged to execute arbitrary code with ring-0 privileges.

A local attacker may exploit this vulnerability to deny service to legitimate users. Other attacks are also likely possible.

- A second integer-overflow vulnerability is reported to exist in the 'vc_resize()' function of the Linux kernel. This vulnerability is reported to exist in the 2.6 and 2.4 kernel trees. Although unconfirmed, due to its nature this issue presumably may be further leveraged to execute arbitrary code with ring-0 privileges.

A local attacker may exploit this vulnerability to deny service to legitimate users. Other attacks are also likely possible.

- A memory leak is reported to exist in 'ip_options_get()' of the 'ip_options.c' kernel source file. This vulnerability is reported to exist in the 2.6, and 2.4 kernel tree.

A local attacker may exploit this vulnerability to consume kernel heap memory resources and in doing so may impact system performance, ultimately resulting in a denial of service to legitimate users.
