Updated varnish packages fix security vulnerabilities :

Varnish before 3.0.5 allows remote attackers to cause a denial of service (child-process crash and temporary caching outage) via a GET request with trailing whitespace characters and no URI (CVE-2013-4484).

Also, the services have been converted from SysV init scripts to systemd-native services, which should allow for more consistent behavior.

This update fixes the following security issue with varnish :

  - bnc#848451, CVE-2013-4484: fixed denial of service flaw     in certain GET requests when using certain     configurations in Varnish Cache handling

The Rocky Linux 9.2 host has packages installed that are affected by multiple vulnerabilities as referenced in the CIQ ciqsa-2026_0502 advisory.

    This advisory aggregates security fixes for the varnish SRPM in CIQ LTS 9.2. It addresses 8 CVEs:

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Rocky Linux 8.6 host has packages installed that are affected by multiple vulnerabilities as referenced in the CIQ ciqsa-2026_0273 advisory.

    This advisory aggregates security fixes for the varnish SRPM in CIQ LTS 8.6. It addresses 9 CVEs:

A denial of service vulnerability was reported in varnish, a state of the art, high-performance web accelerator. With some configurations of varnish a remote attacker could mount a denial of service (child-process crash and temporary caching outage) via a GET request with trailing whitespace characters and no URI.

Varnish Cache Project reports :

If Varnish receives a certain illegal request, and the subroutine 'vcl_error{}' restarts the request, the varnishd worker process will crash with an assert.

The varnishd management process will restart the worker process, but there will be a brief interruption of service and the cache will be emptied, causing more traffic to go to the backend.

We are releasing this advisory because restarting from vcl_error{} is both fairly common and documented.

This is purely a denial of service vulnerability, there is no risk of privilege escalation.

Workaround

Insert this at the top of your VCL file :

sub vcl_error { if (obj.status == 400 || obj.status == 413) { return(deliver); } }

Or add this test at the top of your existing vcl_error{}.

Varnish before 3.0.5 allows remote attackers to cause a denial of service (child-process crash and temporary caching outage) via a GET request with trailing whitespace characters and no URI.

varnish 3.0.3 uses world-readable permissions for the /var/log/varnish/ directory and the log files in the directory, which allows local users to obtain sensitive information by reading the files. NOTE: some of these details are obtained from third party information.

The remote host is affected by the vulnerability described in GLSA-201412-30 (Varnish: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Varnish. Please review       the CVE identifiers referenced below for details.
  Impact :

    A remote attacker could cause a Denial of Service condition via a       specially crafted GET request. Furthermore a local attacker could obtain       sensitive information through insecure permissions on logfiles.
  Workaround :

    There is no known workaround at this time.

  - bnc#839358: Deactivate libpcre JIT
