Problem Description:

Requests to create cryptography sessions using a MAC did not validate the + user-supplied MAC key length. The cryptodev module allocates a buffer whose + size is this user-suppled length.

Impact:

An unprivileged process can trigger a kernel panic.

Problem Description:

A race condition permitted a data structure in the kernel to be used + after it was freed by the cryptodev module.

Impact:

An unprivileged process can overwrite arbitrary kernel memory.

Problem Description:

The SCTP layer does improper checking when an application tries to update + a shared key. Therefore an unprivileged local user can trigger a use-after- + free situation, for example by specific sequences of updating shared keys and + closing the SCTP association.

Impact:

Triggering the use-after-free situation may result in unintended kernel + behaviour including a kernel panic.

Problem Description:

The FTP packet handler in libalias incorrectly calculates some packet + lengths. This may result in disclosing small amounts of memory from the + kernel (for the in-kernel NAT implementation) or from the process space for + natd (for the userspace implementation).

Impact:

A malicious attacker could send specially constructed packets that exploit the + erroneous calculation allowing the attacker to disclose small amount of memory + either from the kernel (for the in-kernel NAT implementation) or from the + process space for natd (for the userspace implementation).

Problem Description:

libalias(3) packet handlers do not properly validate the packet length before + accessing the protocol headers. As a result, if a libalias(3) module does + not properly validate the packet length before accessing the protocol header, + it is possible for an out of bound read or write condition to occur.

Impact:

A malicious attacker could send specially constructed packets that exploit + the lack of validation allowing the attacker to read or write memory either + from the kernel (for the in-kernel NAT implementation) or from the process + space for natd (for the userspace implementation).
