Description

This security bulletin contains information about 2 secuirty vulnerabilities.


1) Resource exhaustion (CVE-ID: CVE-2013-2128)

The vulnerability allows a local authenticated user to perform a denial of service (DoS) attack.

The tcp_read_sock function in net/ipv4/tcp.c in the Linux kernel before 2.6.34 does not properly manage skb consumption, which allows local users to cause a denial of service (system crash) via a crafted splice system call for a TCP socket.


2) Incorrect calculation (CVE-ID: CVE-2011-1573)

The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.

net/sctp/sm_make_chunk.c in the Linux kernel before 2.6.34, when addip_enable and auth_enable are used, does not consider the amount of zero padding during calculation of chunk lengths for (1) INIT and (2) INIT ACK chunks, which allows remote attackers to cause a denial of service (OOPS) via crafted packet data.


Remediation

Install update from vendor's website.
