Description GLSAMaker/CVETool Bot gentoo-dev 2017-10-31 15:05:03 UTC
CVE-2017-5630 (
  PECL in the download utility class in the Installer in PEAR Base System
  v1.10.1 does not validate file types and filenames after a redirect, which
  allows remote HTTP servers to overwrite files via crafted responses, as
  demonstrated by a .htaccess overwrite.

@Maintainers 1.10.3 is in tree, and should contain the fix. Please call for stabilization when ready.

Thank you

I would rather stabilize the latest PEAR-PEAR, but that requires the new dev-php/phpunit to be stable first. I've asked for that as part of bug 635356, and I'll try to remember to check back in here afterwards.

Agree with Redhat's assessment: 

"Since pear's purpose is to download libraries for inclusion in an application, any use of `pear install` or `pear download` implicitly trusts the server. This vulnerability does not significantly extend the trust already given to pear and to servers used with it."
