CVS Tags: pkgsrc-2020Q4-base, pkgsrc-2020Q4, pkgsrc-2020Q3-base, pkgsrc-2020Q3, pkgsrc-2020Q2-base, pkgsrc-2020Q2, pkgsrc-2020Q1-base, pkgsrc-2020Q1, pkgsrc-2019Q4-base, pkgsrc-2019Q4
Update xymon and xymonclient to version 4.3.29.
Add patches to xymon from the xymon code repository to fix compatibility
issues in 4.3.29.
Changes for 4.3.29
Several buffer overflow security issues have been resolved, as well as
a potential XSS attack on certain CGI interfaces. Although the ability
to exploit is limited, all users are urged to upgrade.
The assigned CVE numbers are:
CVE-2019-13451, CVE-2019-13452, CVE-2019-13455, CVE-2019-13473,
CVE-2019-13474, CVE-2019-13484, CVE-2019-13485, CVE-2019-13486
In addition, revisions have been made to a number of places throughout
the code to convert the most common sprintf statements to snprintf for
safer processing, which should reduce the impact of similar parsing.
Additional work on this will continue in the future.
The affected CGIs are:
history.c (overflow of histlogfn) = CVE-2019-13451
reportlog.c (overflow of histlogfn) = CVE-2019-13452
csvinfo.c (overflow of dbfn) = CVE-2019-13273
csvinfo.c (reflected XSS) = CVE-2019-13274
acknowledge.c (overflow of msgline) = CVE-2019-13455
appfeed.c (overflow of errtxt) = CVE-2019-13484
history.c (overflow of selfurl) = CVE-2019-13485
svcstatus.c (overflow of errtxt) = CVE-2019-13486
We would like to thank the University of Cambridge Computer Security
Incident Response Team for their assistance in reporting and helping
resolve these issues.
On Linux, a few additional tmpfs volumes are ignored by default
on new (or unmodified) installs. This includes /run/user/<uid>,
which is a transient, per-session tmpfs on some systems. To re-
enable monitoring for this (if you are running services under
a user with a login session), you may need to edit the analysis.cfg(5)
After upgrade, these partitions will no longer be alerted on or
tracked, and their associated RRD files may also be removed:
/run/user/<uid> (but NOT /run)
/dev (but NOT /dev/shm)
The default hard limit for an incoming message has been raised from
10MB to 64MB
The secure apache config snippet no longer requires a xymongroups file
to be present (and module loaded), since it's not used by default. This
will not affect existing installs.
A --no-cpu-listing option has been added to xymond_client to suppress the
'top' output in cpu test status messages.
The conversation used in SMTP checks has been adjusted to perform a proper
"EHLO" greeting against servers, using the host string 'xymonnet'. If the
string needs to be adjusted, however, see protocols.cfg(5)
"Actual" memory usage (as a percentage) may be >100% on some platforms
in certain situations. This alone will not be tagged as "invalid" data
and should be graphed in RRD.
