CVE-2011-1080
Publication date 25 July 2011
Last updated 24 July 2024
Ubuntu priority
The do_replace function in net/bridge/netfilter/ebtables.c in the Linux kernel before 2.6.39 does not ensure that a certain name field ends with a ‘\0’ character, which allows local users to obtain potentially sensitive information from kernel stack memory by leveraging the CAP_NET_ADMIN capability to replace a table, and then reading a modprobe command line.
From the Ubuntu Security Team
Vasiliy Kulikov discovered that bridge network filtering did not check that name fields were NULL terminated. A local attacker could exploit this to leak contents of kernel stack memory, leading to a loss of privacy.
