CVE-2016-6581 1 Python 2 Hpack, Hyper 2025-04-20 7.8 HIGH 7.5 HIGH
A HTTP/2 implementation built using any version of the Python HPACK library between v1.0.0 and v2.2.0 could be targeted for a denial of service attack, specifically a so-called "HPACK Bomb" attack. This attack occurs when an attacker inserts a header field that is exactly the size of the HPACK dynamic header table into the dynamic header table. The attacker can then send a header block that is simply repeated requests to expand that field in the dynamic table. This can lead to a gigantic compression ratio of 4,096 or better, meaning that 16kB of data can decompress to 64MB of data on the target machine.
CVE-2016-6580 1 Python 1 Python Priority Library 2025-04-20 5.0 MEDIUM 7.5 HIGH
A HTTP/2 implementation built using any version of the Python priority library prior to version 1.2.0 could be targeted by a malicious peer by having that peer assign priority information for every possible HTTP/2 stream ID. The priority tree would happily continue to store the priority information for each stream, and would therefore allocate unbounded amounts of memory. Attempting to actually use a tree like this would also cause extremely high CPU usage to maintain the tree.
CVE-2017-2810 1 Python 1 Tablib 2025-04-20 7.5 HIGH 7.5 HIGH
An exploitable vulnerability exists in the Databook loading functionality of Tablib 0.11.4. A yaml loaded Databook can execute arbitrary python commands resulting in command execution. An attacker can insert python into loaded yaml to trigger this vulnerability.
CVE-2013-7338 2 Apple, Python 2 Mac Os X, Python 2025-04-12 7.1 HIGH N/A
Python before 3.3.4 RC1 allows remote attackers to cause a denial of service (infinite loop and CPU consumption) via a file size value larger than the size of the zip file to the (1) ZipExtFile.read, (2) ZipExtFile.read(n), (3) ZipExtFile.readlines, (4) ZipFile.extract, or (5) ZipFile.extractall function.
CVE-2014-9601 4 Fedoraproject, Opensuse, Oracle and 1 more 4 Fedora, Opensuse, Solaris and 1 more 2025-04-12 5.0 MEDIUM N/A
Pillow before 2.7.0 allows remote attackers to cause a denial of service via a compressed text chunk in a PNG image that has a large size when it is decompressed.
CVE-2014-7185 2 Apple, Python 2 Mac Os X, Python 2025-04-12 6.4 MEDIUM N/A
Integer overflow in bufferobject.c in Python before 2.7.8 allows context-dependent attackers to obtain sensitive information from process memory via a large size and offset in a "buffer" function.
CVE-2014-1830 2 Opensuse, Python 2 Opensuse, Requests 2025-04-12 5.0 MEDIUM N/A
Requests (aka python-requests) before 2.3.0 allows remote servers to obtain sensitive information by reading the Proxy-Authorization header in a redirected request.
CVE-2014-1933 2 Python, Pythonware 2 Pillow, Python Imaging Library 2025-04-12 2.1 LOW N/A
The (1) JpegImagePlugin.py and (2) EpsImagePlugin.py scripts in Python Image Library (PIL) 1.1.7 and earlier and Pillow before 2.3.1 uses the names of temporary files on the command line, which makes it easier for local users to conduct symlink attacks by listing the processes.
CVE-2016-4009 1 Python 1 Pillow 2025-04-12 10.0 HIGH 9.8 CRITICAL
Integer overflow in the ImagingResampleHorizontal function in libImaging/Resample.c in Pillow before 3.1.1 allows remote attackers to have unspecified impact via negative values of the new size, which triggers a heap-based buffer overflow.
CVE-2015-5652 2 Microsoft, Python 2 Windows, Python 2025-04-12 7.2 HIGH N/A
Untrusted search path vulnerability in python.exe in Python through 3.5.0 on Windows allows local users to gain privileges via a Trojan horse readline.pyd file in the current working directory. NOTE: the vendor says "It was determined that this is a longtime behavior of Python that cannot really be altered at this point."
CVE-2014-1932 2 Python, Pythonware 2 Pillow, Python Imaging Library 2025-04-12 4.4 MEDIUM N/A
The (1) load_djpeg function in JpegImagePlugin.py, (2) Ghostscript function in EpsImagePlugin.py, (3) load function in IptcImagePlugin.py, and (4) _copy function in Image.py in Python Image Library (PIL) 1.1.7 and earlier and Pillow before 2.3.1 do not properly create temporary files, which allow local users to overwrite arbitrary files and obtain sensitive information via a symlink attack on the temporary file.
CVE-2014-1829 4 Canonical, Debian, Mageia and 1 more 4 Ubuntu Linux, Debian Linux, Mageia and 1 more 2025-04-12 5.0 MEDIUM N/A
Requests (aka python-requests) before 2.3.0 allows remote servers to obtain a netrc password by reading the Authorization header in a redirected request.
CVE-2014-3589 3 Debian, Opensuse, Python 3 Python-imaging, Opensuse, Pillow 2025-04-12 5.0 MEDIUM N/A
PIL/IcnsImagePlugin.py in Python Imaging Library (PIL) and Pillow before 2.3.2 and 2.5.x before 2.5.2 allows remote attackers to cause a denial of service via a crafted block size.
CVE-2014-3598 2 Opensuse, Python 2 Opensuse, Pillow 2025-04-12 5.0 MEDIUM N/A
The Jpeg2KImagePlugin plugin in Pillow before 2.5.3 allows remote attackers to cause a denial of service via a crafted image.
CVE-2015-2296 3 Canonical, Mageia Project, Python 3 Ubuntu Linux, Mageia, Requests 2025-04-12 6.8 MEDIUM N/A
The resolve_redirects function in sessions.py in requests 2.1.0 through 2.5.3 allows remote attackers to conduct session fixation attacks via a cookie without a host value in a redirect.
CVE-2016-0775 2 Debian, Python 2 Debian Linux, Pillow 2025-04-12 4.3 MEDIUM 6.5 MEDIUM
Buffer overflow in the ImagingFliDecode function in libImaging/FliDecode.c in Pillow before 3.1.1 allows remote attackers to cause a denial of service (crash) via a crafted FLI file.
CVE-2014-0224 9 Fedoraproject, Filezilla-project, Mariadb and 6 more 20 Fedora, Filezilla Server, Mariadb and 17 more 2025-04-12 5.8 MEDIUM 7.4 HIGH
OpenSSL before 0.9.8za, 1.0.0 before 1.0.0m, and 1.0.1 before 1.0.1h does not properly restrict processing of ChangeCipherSpec messages, which allows man-in-the-middle attackers to trigger use of a zero-length master key in certain OpenSSL-to-OpenSSL communications, and consequently hijack sessions or obtain sensitive information, via a crafted TLS handshake, aka the "CCS Injection" vulnerability.
CVE-2013-7040 2 Apple, Python 2 Mac Os X, Python 2025-04-12 4.3 MEDIUM N/A
Python 2.7 before 3.4 only uses the last eight bits of the prefix to randomize hash values, which causes it to compute hash values without restricting the ability to trigger hash collisions predictably and makes it easier for context-dependent attackers to cause a denial of service (CPU consumption) via crafted input to an application that maintains a hash table. NOTE: this vulnerability exists because of an incomplete fix for CVE-2012-1150.
CVE-2016-5636 1 Python 1 Python 2025-04-12 10.0 HIGH 9.8 CRITICAL
Integer overflow in the get_data function in zipimport.c in CPython (aka Python) before 2.7.12, 3.x before 3.4.5, and 3.5.x before 3.5.2 allows remote attackers to have unspecified impact via a negative data size value, which triggers a heap-based buffer overflow.
CVE-2016-1494 3 Fedoraproject, Opensuse, Python 4 Fedora, Leap, Opensuse and 1 more 2025-04-12 5.0 MEDIUM 5.3 MEDIUM
The verify function in the RSA package for Python (Python-RSA) before 3.3 allows attackers to spoof signatures with a small public exponent via crafted signature padding, aka a BERserk attack.
