CVE-2020-26116 7 Canonical, Debian, Fedoraproject and 4 more 9 Ubuntu Linux, Debian Linux, Fedora and 6 more 2023-12-10 6.4 MEDIUM 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-2021-25289 1 Python 1 Pillow 2023-12-10 7.5 HIGH 9.8 CRITICAL
An issue was discovered in Pillow before 8.1.1. TiffDecode has a heap-based buffer overflow when decoding crafted YCbCr files because of certain interpretation conflicts with LibTIFF in RGBA mode. NOTE: this issue exists because of an incomplete fix for CVE-2020-35654.
CVE-2020-35655 2 Fedoraproject, Python 2 Fedora, Pillow 2023-12-10 5.8 MEDIUM 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-2020-35653 3 Debian, Fedoraproject, Python 3 Debian Linux, Fedora, Pillow 2023-12-10 5.8 MEDIUM 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-2020-26137 4 Canonical, Debian, Oracle and 1 more 5 Ubuntu Linux, Debian Linux, Communications Cloud Native Core Network Function Cloud Native Environment and 2 more 2023-12-10 6.4 MEDIUM 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-2021-25290 2 Debian, Python 2 Debian Linux, Pillow 2023-12-10 5.0 MEDIUM 7.5 HIGH
An issue was discovered in Pillow before 8.1.1. In TiffDecode.c, there is a negative-offset memcpy with an invalid size.
CVE-2021-27922 2 Fedoraproject, Python 2 Fedora, Pillow 2023-12-10 5.0 MEDIUM 7.5 HIGH
Pillow before 8.1.1 allows attackers to cause a denial of service (memory consumption) because the reported size of a contained image is not properly checked for an ICNS container, and thus an attempted memory allocation can be very large.
CVE-2021-28363 3 Fedoraproject, Oracle, Python 3 Fedora, Peoplesoft Enterprise Peopletools, Urllib3 2023-12-10 6.4 MEDIUM 6.5 MEDIUM
The urllib3 library 1.26.x before 1.26.4 for Python omits SSL certificate validation in some cases involving HTTPS to HTTPS proxies. The initial connection to the HTTPS proxy (if an SSLContext isn't given via proxy_config) doesn't verify the hostname of the certificate. This means certificates for different servers that still validate properly with the default urllib3 SSLContext will be silently accepted.
CVE-2021-23336 6 Debian, Djangoproject, Fedoraproject and 3 more 12 Debian Linux, Django, Fedora and 9 more 2023-12-10 4.0 MEDIUM 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-2021-28667 2 Python, Stackstorm 2 Python, Stackstorm 2023-12-10 7.1 HIGH 7.5 HIGH
StackStorm before 3.4.1, in some situations, has an infinite loop that consumes all available memory and disk space. This can occur if Python 3.x is used, the locale is not utf-8, and there is an attempt to log Unicode data (from an action or rule name).
CVE-2021-25292 1 Python 1 Pillow 2023-12-10 4.3 MEDIUM 6.5 MEDIUM
An issue was discovered in Pillow before 8.1.1. The PDF parser allows a regular expression DoS (ReDoS) attack via a crafted PDF file because of a catastrophic backtracking regex.
CVE-2021-27921 2 Fedoraproject, Python 2 Fedora, Pillow 2023-12-10 5.0 MEDIUM 7.5 HIGH
Pillow before 8.1.1 allows attackers to cause a denial of service (memory consumption) because the reported size of a contained image is not properly checked for a BLP container, and thus an attempted memory allocation can be very large.
CVE-2020-29396 2 Odoo, Python 2 Odoo, Python 2023-12-10 6.5 MEDIUM 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-2021-25291 1 Python 1 Pillow 2023-12-10 5.0 MEDIUM 7.5 HIGH
An issue was discovered in Pillow before 8.1.1. In TiffDecode.c, there is an out-of-bounds read in TiffreadRGBATile via invalid tile boundaries.
CVE-2021-27923 2 Fedoraproject, Python 2 Fedora, Pillow 2023-12-10 5.0 MEDIUM 7.5 HIGH
Pillow before 8.1.1 allows attackers to cause a denial of service (memory consumption) because the reported size of a contained image is not properly checked for an ICO container, and thus an attempted memory allocation can be very large.
CVE-2021-25293 1 Python 1 Pillow 2023-12-10 5.0 MEDIUM 7.5 HIGH
An issue was discovered in Pillow before 8.1.1. There is an out-of-bounds read in SGIRleDecode.c.
CVE-2020-35654 2 Fedoraproject, Python 2 Fedora, Pillow 2023-12-10 6.8 MEDIUM 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-2021-3177 5 Debian, Fedoraproject, Netapp and 2 more 10 Debian Linux, Fedora, Active Iq Unified Manager and 7 more 2023-12-10 7.5 HIGH 9.8 CRITICAL
Python 3.x through 3.9.1 has a buffer overflow in PyCArg_repr in _ctypes/callproc.c, which may lead to remote code execution in certain Python applications that accept floating-point numbers as untrusted input, as demonstrated by a 1e300 argument to c_double.from_param. This occurs because sprintf is used unsafely.
CVE-2019-20907 7 Canonical, Debian, Fedoraproject and 4 more 8 Ubuntu Linux, Debian Linux, Fedora and 5 more 2023-12-10 5.0 MEDIUM 7.5 HIGH
In Lib/tarfile.py in Python through 3.8.3, an attacker is able to craft a TAR archive leading to an infinite loop when opened by tarfile.open, because _proc_pax lacks header validation.
CVE-2020-10994 3 Canonical, Fedoraproject, Python 3 Ubuntu Linux, Fedora, Pillow 2023-12-10 4.3 MEDIUM 5.5 MEDIUM
In libImaging/Jpeg2KDecode.c in Pillow before 7.1.0, there are multiple out-of-bounds reads via a crafted JP2 file.
