|---|---|---|---|---|---|
| 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-2016-9015 | 1 Python | 1 Urllib3 | 2025-04-20 | 2.6 LOW | 3.7 LOW |
| Versions 1.17 and 1.18 of the Python urllib3 library suffer from a vulnerability that can cause them, in certain configurations, to not correctly validate TLS certificates. This places users of the library with those configurations at risk of man-in-the-middle and information leakage attacks. This vulnerability affects users using versions 1.17 and 1.18 of the urllib3 library, who are using the optional PyOpenSSL support for TLS instead of the regular standard library TLS backend, and who are using OpenSSL 1.1.0 via PyOpenSSL. This is an extremely uncommon configuration, so the security impact of this vulnerability is low. | |||||
| CVE-2017-1000158 | 2 Debian, Python | 2 Debian Linux, Python | 2025-04-20 | 7.5 HIGH | 9.8 CRITICAL |
| CPython (aka Python) up to 2.7.13 is vulnerable to an integer overflow in the PyString_DecodeEscape function in stringobject.c, resulting in heap-based buffer overflow (and possible arbitrary code execution) | |||||
| CVE-2017-9233 | 3 Debian, Libexpat Project, Python | 3 Debian Linux, Libexpat, Python | 2025-04-20 | 5.0 MEDIUM | 7.5 HIGH |
| XML External Entity vulnerability in libexpat 2.2.0 and earlier (Expat XML Parser Library) allows attackers to put the parser in an infinite loop using a malformed external entity definition from an external DTD. | |||||
| 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-2014-4616 | 4 Opensuse, Opensuse Project, Python and 1 more | 4 Opensuse, Opensuse, Python and 1 more | 2025-04-20 | 4.3 MEDIUM | 5.9 MEDIUM |
| Array index error in the scanstring function in the _json module in Python 2.7 through 3.5 and simplejson before 2.6.1 allows context-dependent attackers to read arbitrary process memory via a negative index value in the idx argument to the raw_decode function. | |||||
| 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-2016-3076 | 1 Python | 1 Pillow | 2025-04-20 | 4.3 MEDIUM | 5.5 MEDIUM |
| Heap-based buffer overflow in the j2k_encode_entry function in Pillow 2.5.0 through 3.1.1 allows remote attackers to cause a denial of service (memory corruption) via a crafted Jpeg2000 file. | |||||
| CVE-2017-5992 | 1 Python | 1 Openpyxl | 2025-04-20 | 5.8 MEDIUM | 8.2 HIGH |
| Openpyxl 2.4.1 resolves external entities by default, which allows remote attackers to conduct XXE attacks via a crafted .xlsx document. | |||||
| CVE-2017-17522 | 1 Python | 1 Python | 2025-04-20 | 6.8 MEDIUM | 8.8 HIGH |
| Lib/webbrowser.py in Python through 3.6.3 does not validate strings before launching the program specified by the BROWSER environment variable, which might allow remote attackers to conduct argument-injection attacks via a crafted URL. NOTE: a software maintainer indicates that exploitation is impossible because the code relies on subprocess.Popen and the default shell=False setting | |||||
| 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-2014-2667 | 1 Python | 1 Python | 2025-04-12 | 3.3 LOW | N/A |
| Race condition in the _get_masked_mode function in Lib/os.py in Python 3.2 through 3.5, when exist_ok is set to true and multiple threads are used, might allow local users to bypass intended file permissions by leveraging a separate application vulnerability before the umask has been set to the expected value. | |||||
| 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. | |||||

| Python Image Library (PIL) 1.1.7 and earlier and Pillow 2.3 might allow remote attackers to execute arbitrary commands via shell metacharacters in unspecified vectors related to CVE-2014-1932, possibly JpegImagePlugin.py. | |||||
| 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-2014-1932 | 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-2013-7440 | 1 Python | 1 Python | 2025-04-12 | 4.3 MEDIUM | 5.9 MEDIUM |
| The ssl.match_hostname function in CPython (aka Python) before 2.7.9 and 3.x before 3.3.3 does not properly handle wildcards in hostnames, which might allow man-in-the-middle attackers to spoof servers via a crafted certificate. | |||||
| CVE-2016-5699 | 1 Python | 1 Python | 2025-04-12 | 4.3 MEDIUM | 6.1 MEDIUM |
| CRLF injection vulnerability in the HTTPConnection.putheader function in urllib2 and urllib in CPython (aka Python) before 2.7.10 and 3.x before 3.4.4 allows remote attackers to inject arbitrary HTTP headers via CRLF sequences in a URL. | |||||
