Re: Linux-audit Digest, Vol 142, Issue 18

by aung

Hi All, Please ask me one question regarding about of RHEL security. To hack RHEL root privilege is possible or not ? Even this system didn't try to patch update CVE,RHSA and so on. Thanks in advance for your feedback.

Questions about the standard (Google Summer of Code Project)

by Mateusz Piotrowski

Hi, I participate in Google Summer of Code and my project involves converting Linux Audit logs to BSM logs. As I was writing a parser and converter I stumbled upon a couple of things I do not understand and I cannot find in the documentation: 1. Where are all the elements like auditd start, user, etc. listed? I cannot find any document which specifies what can occurs between the colon (separating the type and the msg=audit(…) from the fields) and the record’s fields. 2. Why are there two spaces between the colon and the first field in records of type=CWD and a field cwd=“/root”? Here’s an example: type=CWD msg=audit(1464013682.961:409): cwd="/root” 3. According to Red Hat’s documentation[1]: > Each record consists of several name=value pairs separated by a white space or a comma. a) Is a white space always a space? Can be any white space like the tab character? b) Why do some records are separated by a comma and a whitespace? Example: type=DAEMON_START msg=audit(1363713609.192:5426): auditd start, ver=2.2 format=raw kernel=2.6.32-358.2.1.el6.x86_64 auid=500 pid=4979 subj=unconfined_u:system_r:auditd_t:s0 res=success I’ve posted the question on Unix & Linux SE: [3]. 4. Is it possible that there are duplicate fields in a record? Something like (which doesn’t make much sense obviously): type=CWD msg=audit(1464013682.961:409): cwd="/root” cwd=“/usr” I’ve already asked a similar question on Unix & Linux SE: [4]. 5. Is there a document which answers my questions? That would be cool! Thanks a lot for help! Cheers!

audit 2.6.5 released

by Steve Grubb

Hello, I've just released a new version of the audit daemon. It can be downloaded from http://people.redhat.com/sgrubb/audit. It will also be in rawhide soon. The ChangeLog is: - Correct the header length for dispatched events - Revise buffer handling in auditd to fix dispatched events - Fix spelling in man pages - Add documentation link to systemd unit file - Correct af_unix pathname detection in ausearch/report - Add remote_ended info to audisp-remote stat dump This release fixes truncated records passed to audisp plugins when the old event format was used. It was also discovered that ausearch was not picking up patchnames for af_unix sockets and this was corrected. Besides that there were several documentation fixups. Please let me know if you run across any problems with this release. -Steve

euid missing

by Chris Nandor

As mentioned in previous e-mail, we want to log what users do as root. I have these two rules, only: -a exit,always -F arch=b32 -F euid=0 -F auid>=0 -F auid!=4294967295 -S execve -k rootcmd -a exit,always -F arch=b64 -F euid=0 -F auid>=0 -F auid!=4294967295 -S execve -k rootcmd But this line shows up: node=grax.sea.marchex.com type=ANOM_ABEND msg=audit(1468426871.752:3282575): auid=811 uid=811 gid=811 ses=12 pid=18504 comm="chromium-browse" reason="seccomp" sig=0 syscall=91 compat=0 ip=0x7f296c759c77 code=0x50001 My guess is that it is because euid is missing; maybe euid=0 is true if euid is null? I could put uid=0, instead of euid ... but that isn't exactly what I want, I think. Is there a way to have the rule require euid actually be 0? --Chris

RE: Upgrading audit package

by Bhagwat, Shriniketan Manjunath

Hi Steve, As requested in my previous email, I am interested in understanding the relation between Linux audit kernel and user space audit. Will a audit kernel available with Linux kernel 2.6.32 compatible with user space audit 2.6.X? I understand you might be busy with your regular schedules. :-) Regards, Ketan From: Bhagwat, Shriniketan Manjunath Sent: Monday, July 11, 2016 1:48 PM To: 'Steve Grubb' <sgrubb(a)redhat.com> Cc: linux-audit(a)redhat.com Subject: Upgrading audit package Hi Steve, I am using audit in my development environment. My development environment is as below. RHEL 5.2 with kernel 2.6.32-431.el6.x86_64 and audit-2.2-2.el6.x86_64. SUSE 11 SP3 with kernel 3.0.76-0.11-default and audit-1.8-0.30.1 As I understand the above audit packages I am using in my environment are user space audit. I want to upgrade it to the latest version. If I upgrade the audit packages to latest version 2.6.X will there be any issues? Linux Audit kernel available with kernel 2.6.32-431.el6.x86_64 and 3.0.76-0.11 are compatible with user space audit 2.6.X? In your opinion what is the suitable audit package for my environment to upgrade? If these topics are already documented please guide me to the documentation. Regards, Ketan

[PATCH] capabilities: audit capability use

by Topi Miettinen

There are many basic ways to control processes, including capabilities, cgroups and resource limits. However, there are far fewer ways to find out useful values for the limits, except blind trial and error. Currently, there is no way to know which capabilities are actually used. Even the source code is only implicit, in-depth knowledge of each capability must be used when analyzing a program to judge which capabilities the program will exercise. Generate an audit message at system call exit, when capabilities are used. This can then be used to configure capability sets for services by a software developer, maintainer or system administrator. Test case demonstrating basic capability monitoring with the new message types 1330 and 1331 and how the cgroups are displayed (boot to rdshell): BusyBox v1.22.1 (Debian 1:1.22.0-19) built-in shell (ash) Enter 'help' for a list of built-in commands.

Upgrading audit package

by Bhagwat, Shriniketan Manjunath

Hi Steve, I am using audit in my development environment. My development environment is as below. RHEL 5.2 with kernel 2.6.32-431.el6.x86_64 and audit-2.2-2.el6.x86_64. SUSE 11 SP3 with kernel 3.0.76-0.11-default and audit-1.8-0.30.1 As I understand the above audit packages I am using in my environment are user space audit. I want to upgrade it to the latest version. If I upgrade the audit packages to latest version 2.6.X will there be any issues? Linux Audit kernel available with kernel 2.6.32-431.el6.x86_64 and 3.0.76-0.11 are compatible with user space audit 2.6.X? In your opinion what is the suitable audit package for my environment to upgrade? If these topics are already documented please guide me to the documentation. Regards, Ketan

[PATCH 0/3] Misc build fixes

by Thomas Petazzoni

Hello, The first two patches in this series fix misc build issues of audit with old kernel headers. The last patch fixes warnings encountered when running autoreconf on audit's configure.ac. As a side note, are there any plans to switch the audit development to a Git repository? Having to switch back to Subversion is really painful, which is why the patches in this series are Git-formatted. Thanks! Thomas Thomas Petazzoni (3): lib/gen_tables.c: define EHWPOISON when not available Fix usage of audit_status.feature_bitmap configure.ac: add subdir-objects configure.ac | 3 ++- lib/gen_tables.c | 9 +++++++++ lib/libaudit.c | 2 +- 3 files changed, 12 insertions(+), 2 deletions(-) -- 2.7.4
