Title:
libapparmor aalogparse memory leak
Status in AppArmor Linux application security framework:
Fix Released
Status in AppArmor 2.8 series:
Fix Released
Status in apparmor package in Ubuntu:
Fix Released
Bug description:
My kern.log is filled by lots of messages so aa-notify tries to parse
them on first run.
My OS is going down when there's no memory left because aa-notify
leaks.
I've found that leak is in /usr/bin/aa-notify file in function
parse_message.
If I comment lines from
my ($test) = LibAppArmorc::parse_record($msg);
to
LibAppArmorc::free_record($test);
then all goes fine. Program parses file and no memory leak is happened.
Do I've got sources of my version (libapparmor-perl (2.8.0-5.1) from ubuntu) and found that some variables from aa_log_record struct were not freed by the free_record function. These are
char *net_local_addr;
char *net_foreign_addr;
Could this be a reason of a leak?
I haven't much time right now to compile and run tests. So I posted
just information I've found and commented lines in bugged function to
get my system working.
