CVE-2019-5010

An exploitable denial-of-service vulnerability exists in the X509 certificate parser of Python.org Python 2.7.11 / 3.6.6. A specially crafted X509 certificate can cause a NULL pointer dereference, resulting in a denial of service. An attacker can initiate or accept TLS connections using crafted certificates to trigger this vulnerability.

An exploitable denial-of-service vulnerability exists in the X509 certificate parser of Python.org Python 2.7.11 / 3.7.2. A specially crafted X509 certificate can cause a NULL pointer dereference, resulting in a denial of service. An attacker can initiate or accept TLS connections using crafted certificates to trigger this vulnerability (CVE-2019-5010).

Python's elementtree C accelerator failed to initialise Expat's hash salt during initialization. This could make it easy to conduct denial of service attacks against Expat by contructing an XML document that would cause pathological hash collisions in Expat's internal data structures, consuming large amounts CPU and RAM (CVE-2018-14647).

Modules/_pickle.c in Python before 3.5.7 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-2018-20406).

A null pointer dereference vulnerability was found in the certificate parsing code in Python. This causes a denial of service to applications when parsing specially crafted certificates. This vulnerability is unlikely to be triggered if application enables SSL/TLS certificate validation and accepts certificates only from trusted root certificate authorities (CVE-2019-5010).

A vulnerability was found in Python 3.x through 3.5.7. An improper Handling of Unicode Encoding (with an incorrect netloc) during NFKC normalization could lead to an Information Disclosure (credentials, cookies, etc. that are cached against a given hostname) in the urllib.parse.urlsplit, urllib.parse.urlparse components. A specially crafted URL could be incorrectly parsed to locate cookies or authentication data and send that information to a different host than when parsed correctly (CVE-2019-9636).

The python3 package has been updated to version 3.5.7, fixing these and other issues.

This update was imported from the SUSE:SLE-15:Update update project.

This update for python3 fixes the following issues:

• Fixed CVE-2020-27619 (bsc#1178009), where Lib/test/multibytecodec_support calls eval() on content retrieved via HTTP.
• Change setuptools and pip version numbers according to new wheels
• Handful of changes to make python36 compatible with SLE15 and SLE12 (jsc#ECO-2799, jsc#SLE-13738)
• add triplets for mips-r6 and riscv
• RISC-V needs CTYPES_PASS_BY_REF_HACK

Update to 3.6.12 (bsc#1179193)

• Ensure python3.dll is loaded from correct locations when Python is embedded
• The hash() methods of ipaddress.IPv4Interface and ipaddress.IPv6Interface incorrectly generated constant hash values of 32 and 128 respectively. This resulted in always causing hash collisions. The fix uses hash() to generate hash values for the tuple of (address, mask length, network address).
• Prevent http header injection by rejecting control characters in http.client.putrequest(…).
• Unpickling invalid NEWOBJ_EX opcode with the C implementation raises now UnpicklingError instead of crashing.
• Avoid infinite loop when reading specially crafted TAR files using the tarfile module

• This release also fixes CVE-2020-26116 (bsc#1177211) and CVE-2019-20907 (bsc#1174091).

Update to 3.6.11:

• Disallow CR or LF in email.headerregistry. Address arguments to guard against header injection attacks.
• Disallow control characters in hostnames in http.client, addressing CVE-2019-18348. Such potentially malicious header injection URLs now cause a InvalidURL to be raised. (bsc#1155094)
• CVE-2020-8492: The AbstractBasicAuthHandler class of the urllib.request module uses an inefficient regular expression which can be exploited by an attacker to cause a denial of service. Fix the regex to prevent the catastrophic backtracking. Vulnerability reported by Ben Caller and Matt Schwager.
