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-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-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-2016-0740 2 Debian, Python 2 Debian Linux, Pillow 2025-04-12 4.3 MEDIUM 6.5 MEDIUM
Buffer overflow in the ImagingLibTiffDecode function in libImaging/TiffDecode.c in Pillow before 3.1.1 allows remote attackers to overwrite memory via a crafted TIFF file.
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.
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-2016-9189 2 Debian, Python 2 Debian Linux, Pillow 2025-04-12 4.3 MEDIUM 5.5 MEDIUM
Pillow before 3.3.2 allows context-dependent attackers to obtain sensitive information by using the "crafted image file" approach, related to an "Integer Overflow" issue affecting the Image.core.map_buffer in map.c component.
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-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-2016-2533 3 Debian, Python, Python Imaging Project 3 Debian Linux, Pillow, Python Imaging 2025-04-12 4.3 MEDIUM 6.5 MEDIUM
Buffer overflow in the ImagingPcdDecode function in PcdDecode.c in Pillow before 3.1.1 and Python Imaging Library (PIL) 1.1.7 and earlier allows remote attackers to cause a denial of service (crash) via a crafted PhotoCD file.
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-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-2016-0718 9 Apple, Canonical, Debian and 6 more 14 Mac Os X, Ubuntu Linux, Debian Linux and 11 more 2025-04-12 7.5 HIGH 9.8 CRITICAL
Expat allows context-dependent attackers to cause a denial of service (crash) or possibly execute arbitrary code via a malformed input document, which triggers a buffer overflow.
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-2014-2667 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.
