The patches LGTM. I'm confused by CVE-2016-4658, the only "affected products" seem to be Apple-based platforms, yet the code itself does not seem platform-specific. And it looks like a serious vulnerability. The other patch is less severe, but at least has some references in free software circles. I'd say push them. Should it be grafted, or can we wait for the next 'core-updates' evaluation? I did not look into the other Debian patches. > > Leo Famulari (1): > gnu: libxml: Fix CVE-2016-{4658,5131}. > > gnu/local.mk | 2 + > gnu/packages/patches/libxml2-CVE-2016-4658.patch | 257 +++++++++++++++++= ++++++ > gnu/packages/patches/libxml2-CVE-2016-5131.patch | 218 +++++++++++++++++= ++ > gnu/packages/xml.scm | 2 + > 4 files changed, 479 insertions(+) > create mode 100644 gnu/packages/patches/libxml2-CVE-2016-4658.patch > create mode 100644 gnu/packages/patches/libxml2-CVE-2016-5131.patch > > --=20 > 2.11.0 --=-=-= Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQEzBAEBCgAdFiEEu7At3yzq9qgNHeZDoqBt8qM6VPoFAlheiK8ACgkQoqBt8qM6 VPp+nwgAjXfJ02owPaP0M+9Ls20OSOdEuK8Z7gWQ0k9BGrTbAaTIWTPK83sxE1WF Skd1fPeTzxtjFSaTDE99pV5OKt8BDqUFTU2aMM44Wc9WFOOM1kB2wfToep6GAdSe QOuu8ptGDwYJg5nDbXRS+JPiwVDX1x0iYa8postkHbRetm+SBDqhrDrJVKK/aFNj vSLH1+jBDdsXIhJFTaRT+tSF4Xg2b3K/9SyKg0+hl9KYVXxkuf2BYO8MJdm2SGbP /zWl5WYAlJQ4KPE2cwVaF8UNhtFEPGybECNuw6rdnsWqdTtgtg7B8q+B331g7klz JozOVAP0Mw19VBTzyjjDb0kTooarEA== =N7F8 -----END PGP SIGNATURE----- --=-=-=--
