DLA-1490-1 php5 -- LTS security update

Date Reported:

01 Sep 2018

Affected Packages:

php5

Vulnerable:

Yes

Security database references:

In the Debian bugtracking system: Bug 890266.
In Mitre's CVE dictionary: CVE-2018-14851, CVE-2018-14883.

More information:

Two vulnerabilities have been discovered in php5, a server-side, HTML-embedded scripting language. One (CVE-2018-14851) results in a potential denial of service (out-of-bounds read and application crash) via a crafted JPEG file. The other (CVE-2018-14883) is an Integer Overflow that leads to a heap-based buffer over-read.

Additionally, a previously introduced patch for CVE-2017-7272 was found to negatively affect existing PHP applications (#890266). As a result of the negative effects and the fact that the security team has marked the CVE in question as "ignore," the patch has been dropped.

For Debian 8 Jessie, these problems have been fixed in version 5.6.37+dfsg-0+deb8u1.

We recommend that you upgrade your php5 packages.
