The following updates has been released for Debian:

[DLA 384-1] inspircd security and regression update
[DSA 3443-1] libpng security update
[DSA 3444-1] wordpress security update
[DSA 3445-1] pygments security update

[DLA 384-1] inspircd security and regression update

Package        : inspircd
Version        : 1.1.22+dfsg-4+squeeze3
CVE ID         : CVE-2015-8702
Debian Bug     : 668253

It was discovered that InspIRCd did not validate the names in DNS
responses before using them in inter-server communication.  A remote
attacker controlling the reverse DNS server for an IRC client could
use this for denial of service or possibly for privilege escalation on
the IRC network.

InspIRCd appears to have been completely unusable since version
1.1.22+dfsg-4+squeeze1 due to a bug in its build system triggered by
(e)glibc versions newer than 2.9.  This has also been fixed.

Several vulnerabilities have been discovered in the libpng PNG library.
The Common Vulnerabilities and Exposures project identifies the
following problems:

CVE-2015-8472

It was discovered that the original fix for CVE-2015-8126 was
incomplete and did not detect a potential overrun by applications
using png_set_PLTE directly. A remote attacker can take advantage of
this flaw to cause a denial of service (application crash).

CVE-2015-8540

Xiao Qixue and Chen Yu discovered a flaw in the png_check_keyword
function. A remote attacker can potentially take advantage of this
flaw to cause a denial of service (application crash).

For the oldstable distribution (wheezy), these problems have been fixed
in version 1.2.49-1+deb7u2.

For the stable distribution (jessie), these problems have been fixed in
version 1.2.50-2+deb8u2.

We recommend that you upgrade your libpng packages.
