CVE-2021-28678 2 Fedoraproject, Python 2 Fedora, Pillow 2024-11-21 4.3 MEDIUM 5.5 MEDIUM
An issue was discovered in Pillow before 8.2.0. For BLP data, BlpImagePlugin did not properly check that reads (after jumping to file offsets) returned data. This could lead to a DoS where the decoder could be run a large number of times on empty data.
CVE-2021-28677 2 Fedoraproject, Python 2 Fedora, Pillow 2024-11-21 5.0 MEDIUM 7.5 HIGH
An issue was discovered in Pillow before 8.2.0. For EPS data, the readline implementation used in EPSImageFile has to deal with any combination of \r and \n as line endings. It used an accidentally quadratic method of accumulating lines while looking for a line ending. A malicious EPS file could use this to perform a DoS of Pillow in the open phase, before an image was accepted for opening.
CVE-2021-28676 2 Fedoraproject, Python 2 Fedora, Pillow 2024-11-21 5.0 MEDIUM 7.5 HIGH
An issue was discovered in Pillow before 8.2.0. For FLI data, FliDecode did not properly check that the block advance was non-zero, potentially leading to an infinite loop on load.
CVE-2021-28675 2 Fedoraproject, Python 2 Fedora, Pillow 2024-11-21 4.3 MEDIUM 5.5 MEDIUM
An issue was discovered in Pillow before 8.2.0. PSDImagePlugin.PsdImageFile lacked a sanity check on the number of input layers relative to the size of the data block. This could lead to a DoS on Image.open prior to Image.load.
CVE-2021-28667 2 Python, Stackstorm 2 Python, Stackstorm 2024-11-21 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-2021-28363 3 Fedoraproject, Oracle, Python 3 Fedora, Peoplesoft Enterprise Peopletools, Urllib3 2024-11-21 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-2021-27923 2 Fedoraproject, Python 2 Fedora, Pillow 2024-11-21 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-2021-27922 2 Fedoraproject, Python 2 Fedora, Pillow 2024-11-21 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-2021-27921 2 Fedoraproject, Python 2 Fedora, Pillow 2024-11-21 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-2021-25293 1 Python 1 Pillow 2024-11-21 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-2021-25292 1 Python 1 Pillow 2024-11-21 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-2021-25291 1 Python 1 Pillow 2024-11-21 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-2021-25290 2 Debian, Python 2 Debian Linux, Pillow 2024-11-21 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-2021-25289 1 Python 1 Pillow 2024-11-21 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-2021-25288 2 Fedoraproject, Python 2 Fedora, Pillow 2024-11-21 6.4 MEDIUM 9.1 CRITICAL
An issue was discovered in Pillow before 8.2.0. There is an out-of-bounds read in J2kDecode, in j2ku_gray_i.
CVE-2021-25287 2 Fedoraproject, Python 2 Fedora, Pillow 2024-11-21 6.4 MEDIUM 9.1 CRITICAL
An issue was discovered in Pillow before 8.2.0. There is an out-of-bounds read in J2kDecode, in j2ku_graya_la.
CVE-2021-23437 2 Fedoraproject, Python 2 Fedora, Pillow 2024-11-21 5.0 MEDIUM 7.5 HIGH
The package pillow 5.2.0 and before 8.3.2 are vulnerable to Regular Expression Denial of Service (ReDoS) via the getrgb function.
CVE-2021-23336 6 Debian, Djangoproject, Fedoraproject and 3 more 12 Debian Linux, Django, Fedora and 9 more 2024-11-21 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-2020-8492 5 Canonical, Debian, Fedoraproject and 2 more 5 Ubuntu Linux, Debian Linux, Fedora and 2 more 2024-11-21 7.1 HIGH 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 4.3 MEDIUM 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.
