CVE-2021-23336 7 Debian, Djangoproject, Fedoraproject and 4 more 14 Debian Linux, Django, Fedora and 11 more 2024-11-21 5.9 Medium
The package python/cpython from 0 and before 3.6.13, from 3.7.0 and before 3.7.10, from 3.8.0 and before 3.8.8, from 3.9.0 and before 3.9.2 are vulnerable to Web Cache Poisoning via urllib.parse.parse_qsl and urllib.parse.parse_qs by using a vector called parameter cloaking. When the attacker can separate query parameters using a semicolon (;), they can cause a difference in the interpretation of the request between the proxy (running with default configuration) and the server. This can result in malicious requests being cached as completely safe ones, as the proxy would usually not see the semicolon as a separator, and therefore would not include it in a cache key of an unkeyed parameter.
CVE-2020-8492 6 Canonical, Debian, Fedoraproject and 3 more 7 Ubuntu Linux, Debian Linux, Fedora and 4 more 2024-11-21 6.5 Medium
Python 2.7 through 2.7.17, 3.5 through 3.5.9, 3.6 through 3.6.10, 3.7 through 3.7.6, and 3.8 through 3.8.1 allows an HTTP server to conduct Regular Expression Denial of Service (ReDoS) attacks against a client because of urllib.request.AbstractBasicAuthHandler catastrophic backtracking.
CVE-2020-8315 1 Python 1 Python 2024-11-21 5.5 Medium
In Python (CPython) 3.6 through 3.6.10, 3.7 through 3.7.6, and 3.8 through 3.8.1, an insecure dependency load upon launch on Windows 7 may result in an attacker's copy of api-ms-win-core-path-l1-1-0.dll being loaded and used instead of the system's copy. Windows 8 and later are unaffected.
CVE-2020-7212 1 Python 1 Urllib3 2024-11-21 7.5 High
The _encode_invalid_chars function in util/url.py in the urllib3 library 1.25.2 through 1.25.7 for Python allows a denial of service (CPU consumption) because of an inefficient algorithm. The percent_encodings array contains all matches of percent encodings. It is not deduplicated. For a URL of length N, the size of percent_encodings may be up to O(N). The next step (normalize existing percent-encoded bytes) also takes up to O(N) for each step, so the total time is O(N^2). If percent_encodings were deduplicated, the time to compute _encode_invalid_chars would be O(kN), where k is at most 484 ((10+6*2)^2).
CVE-2020-5313 5 Canonical, Debian, Fedoraproject and 2 more 6 Ubuntu Linux, Debian Linux, Fedora and 3 more 2024-11-21 7.1 High

CVE-2020-5312 5 Canonical, Debian, Fedoraproject and 2 more 7 Ubuntu Linux, Debian Linux, Fedora and 4 more 2024-11-21 9.8 Critical
libImaging/PcxDecode.c in Pillow before 6.2.2 has a PCX P mode buffer overflow.
CVE-2020-5311 5 Canonical, Debian, Fedoraproject and 2 more 7 Ubuntu Linux, Debian Linux, Fedora and 4 more 2024-11-21 9.8 Critical
libImaging/SgiRleDecode.c in Pillow before 6.2.2 has an SGI buffer overflow.
CVE-2020-5310 4 Canonical, Fedoraproject, Python and 1 more 4 Ubuntu Linux, Fedora, Pillow and 1 more 2024-11-21 8.8 High
libImaging/TiffDecode.c in Pillow before 6.2.2 has a TIFF decoding integer overflow, related to realloc.
CVE-2020-35655 3 Fedoraproject, Python, Redhat 3 Fedora, Pillow, Enterprise Linux 2024-11-21 5.4 Medium
In Pillow before 8.1.0, SGIRleDecode has a 4-byte buffer over-read when decoding crafted SGI RLE image files because offsets and length tables are mishandled.
CVE-2020-35654 3 Fedoraproject, Python, Redhat 3 Fedora, Pillow, Quay 2024-11-21 8.8 High
In Pillow before 8.1.0, TiffDecode has a heap-based buffer overflow when decoding crafted YCbCr files because of certain interpretation conflicts with LibTIFF in RGBA mode.
CVE-2020-35653 4 Debian, Fedoraproject, Python and 1 more 5 Debian Linux, Fedora, Pillow and 2 more 2024-11-21 7.1 High
In Pillow before 8.1.0, PcxDecode has a buffer over-read when decoding a crafted PCX file because the user-supplied stride value is trusted for buffer calculations.
CVE-2020-29396 2 Odoo, Python 2 Odoo, Python 2024-11-21 8.8 High
A sandboxing issue in Odoo Community 11.0 through 13.0 and Odoo Enterprise 11.0 through 13.0, when running with Python 3.6 or later, allows remote authenticated users to execute arbitrary code, leading to privilege escalation.
CVE-2020-27619 4 Fedoraproject, Oracle, Python and 1 more 5 Fedora, Communications Cloud Native Core Network Function Cloud Native Environment, Python and 2 more 2024-11-21 9.8 Critical
In Python 3 through 3.9.0, the Lib/test/multibytecodec_support.py CJK codec tests call eval() on content retrieved via HTTP.
CVE-2020-26137 5 Canonical, Debian, Oracle and 2 more 8 Ubuntu Linux, Debian Linux, Communications Cloud Native Core Network Function Cloud Native Environment and 5 more 2024-11-21 6.5 Medium
urllib3 before 1.25.9 allows CRLF injection if the attacker controls the HTTP request method, as demonstrated by inserting CR and LF control characters in the first argument of putrequest(). NOTE: this is similar to CVE-2020-26116.
CVE-2020-26116 8 Canonical, Debian, Fedoraproject and 5 more 12 Ubuntu Linux, Debian Linux, Fedora and 9 more 2024-11-21 7.2 High
http.client in Python 3.x before 3.5.10, 3.6.x before 3.6.12, 3.7.x before 3.7.9, and 3.8.x before 3.8.5 allows CRLF injection if the attacker controls the HTTP request method, as demonstrated by inserting CR and LF control characters in the first argument of HTTPConnection.request.
CVE-2020-15801 3 Microsoft, Netapp, Python 3 Windows, Max Data, Python 2024-11-21 9.8 Critical
In Python 3.8.4, sys.path restrictions specified in a python38._pth file are ignored, allowing code to be loaded from arbitrary locations. The <executable-name>._pth file (e.g., the python._pth file) is not affected.
CVE-2020-15523 3 Microsoft, Netapp, Python 3 Windows, Snapcenter, Python 2024-11-21 7.8 High
In Python 3.6 through 3.6.10, 3.7 through 3.7.8, 3.8 through 3.8.4rc1, and 3.9 through 3.9.0b4 on Windows, a Trojan horse python3.dll might be used in cases where CPython is embedded in a native application. This occurs because python3X.dll may use an invalid search path for python3.dll loading (after Py_SetPath has been used). NOTE: this issue CANNOT occur when using python.exe from a standard (non-embedded) Python installation on Windows.
CVE-2020-14422 5 Fedoraproject, Opensuse, Oracle and 2 more 6 Fedora, Leap, Enterprise Manager Ops Center and 3 more 2024-11-21 5.9 Medium
Lib/ipaddress.py in Python through 3.8.3 improperly computes hash values in the IPv4Interface and IPv6Interface classes, which might allow a remote attacker to cause a denial of service if an application is affected by the performance of a dictionary containing IPv4Interface or IPv6Interface objects, and this attacker can cause many dictionary entries to be created. This is fixed in: v3.5.10, v3.5.10rc1; v3.6.12; v3.7.9; v3.8.4, v3.8.4rc1, v3.8.5, v3.8.6, v3.8.6rc1; v3.9.0, v3.9.0b4, v3.9.0b5, v3.9.0rc1, v3.9.0rc2.
CVE-2020-13388 1 Python 1 Jw.util 2024-11-21 9.8 Critical
An exploitable vulnerability exists in the configuration-loading functionality of the jw.util package before 2.3 for Python. When loading a configuration with FromString or FromStream with YAML, one can execute arbitrary Python code, resulting in OS command execution, because safe_load is not used.
CVE-2020-11538 4 Canonical, Fedoraproject, Python and 1 more 7 Ubuntu Linux, Fedora, Pillow and 4 more 2024-11-21 8.1 High
In libImaging/SgiRleDecode.c in Pillow through 7.0.0, a number of out-of-bounds reads exist in the parsing of SGI image files, a different issue than CVE-2020-5311.
