Description

The (1) IPv4 and (2) IPv6 implementations in the Linux kernel before 3.1 use a modified MD4 algorithm to generate sequence numbers and Fragment Identification values, which makes it easier for remote attackers to cause a denial of service (disrupted networking) or hijack network sessions by predicting these values and sending crafted packets.

Affected configurations

• linux linux kernel (< 3.1) • redhat enterprise linux 4.0 • f5 arx (>= 6.0.0 <= 6.4.0) • f5 big-ip access policy manager (>= 10.1.0 <= 10.2.4) • f5 big-ip access policy manager (>= 11.0.0 <= 11.1.0) • f5 big-ip analytics (>= 11.0.0 <= 11.1.0) • f5 big-ip application security manager (>= 10.0.0 <= 10.2.4) • f5 big-ip application security manager (>= 11.0.0 <= 11.1.0) • f5 big-ip edge gateway (>= 10.1.0 <= 10.2.4) • f5 big-ip edge gateway (>= 11.0.0 <= 11.1.0) • f5 big-ip global traffic manager (>= 10.0.0 <= 10.2.4) • f5 big-ip global traffic manager (>= 11.0.0 <= 11.1.0) • f5 big-ip link controller (>= 10.0.0 <= 10.2.4) • f5 big-ip link controller (>= 11.0.0 <= 11.1.0) • f5 big-ip local traffic manager (>= 10.0.0 <= 10.2.4) • f5 big-ip local traffic manager (>= 11.0.0 <= 11.1.0) • f5 big-ip protocol security module (>= 10.0.0 <= 10.2.4) • f5 big-ip protocol security module (>= 11.0.0 <= 11.1.0) • f5 big-ip wan optimization manager (>= 10.0.0 <= 10.2.4) • f5 big-ip wan optimization manager (>= 11.0.0 <= 11.1.0) • f5 big-ip webaccelerator (>= 10.0.0 <= 10.2.4) • f5 big-ip webaccelerator (>= 11.0.0 <= 11.1.0) • f5 enterprise manager (>= 2.1.0 <= 2.3.0) • f5 enterprise manager 3.0.0 • f5 firepass (>= 6.0.0 <= 6.1.0) • f5 firepass 7.0.0
