-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Package : python3.4 Version : 3.4.2-1+deb8u2 CVE ID : CVE-2016-0772 CVE-2016-5636 CVE-2016-5699 CVE-2018-20406 CVE-2019-5010
This DLA fixes a a problem parsing x509 certificates, an pickle integer overflow, and some other minor issues: CVE-2016-0772 The smtplib library in CPython does not return an error when StartTLS fails, which might allow man-in-the-middle attackers to bypass the TLS protections by leveraging a network position between the client and the registry to block the StartTLS command, aka a "StartTLS stripping attack." CVE-2016-5636 Integer overflow in the get_data function in zipimport.c in CPython allows remote attackers to have unspecified impact via a negative data size value, which triggers a heap-based buffer overflow. CVE-2016-5699 CRLF injection vulnerability in the HTTPConnection.putheader function in urllib2 and urllib in CPython allows remote attackers to inject arbitrary HTTP headers via CRLF sequences in a URL. CVE-2018-20406 Modules/_pickle.c has an integer overflow via a large LONG_BINPUT value that is mishandled during a "resize to twice the size" attempt. This issue might cause memory exhaustion, but is only relevant if the pickle format is used for serializing tens or hundreds of gigabytes of data. CVE-2019-5010 NULL pointer dereference using a specially crafted X509 certificate. For Debian 8 "Jessie", these problems have been fixed in version 3.4.2-1+deb8u2. We recommend that you upgrade your python3.4 packages.
