CVE-2018-1060 5 Canonical, Debian, Fedoraproject and 2 more 8 Ubuntu Linux, Debian Linux, Fedora and 5 more 2022-07-28 5.0 MEDIUM 7.5 HIGH
python before versions 2.7.15, 3.4.9, 3.5.6rc1, 3.6.5rc1 and 3.7.0 is vulnerable to catastrophic backtracking in pop3lib's apop() method. An attacker could use this flaw to cause denial of service.
CVE-2017-9233 3 Debian, Libexpat Project, Python 3 Debian Linux, Libexpat, Python 2022-07-28 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-2016-1000110 3 Debian, Fedoraproject, Python 3 Debian Linux, Fedora, Python 2022-07-28 5.8 MEDIUM 6.1 MEDIUM
The CGIHandler class in Python before 2.7.12 does not protect against the HTTP_PROXY variable name clash in a CGI script, which could allow a remote attacker to redirect HTTP requests.
CVE-2019-15903 2 Libexpat Project, Python 2 Libexpat, Python 2022-07-28 5.0 MEDIUM 7.5 HIGH
In libexpat before 2.2.8, crafted XML input could fool the parser into changing from DTD parsing to document parsing too early; a consecutive call to XML_GetCurrentLineNumber (or XML_GetCurrentColumnNumber) then resulted in a heap-based buffer over-read.
CVE-2019-5010 4 Debian, Opensuse, Python and 1 more 7 Debian Linux, Leap, Python and 4 more 2022-07-28 5.0 MEDIUM 7.5 HIGH
An exploitable denial-of-service vulnerability exists in the X509 certificate parser of Python.org Python 2.7.11 / 3.6.6. A specially crafted X509 certificate can cause a NULL pointer dereference, resulting in a denial of service. An attacker can initiate or accept TLS connections using crafted certificates to trigger this vulnerability.
CVE-2019-20907 7 Canonical, Debian, Fedoraproject and 4 more 8 Ubuntu Linux, Debian Linux, Fedora and 5 more 2022-07-28 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-2021-29921 2 Oracle, Python 6 Communications Cloud Native Core Automated Test Suite, Communications Cloud Native Core Binding Support Function, Communications Cloud Native Core Network Slice Selection Function and 3 more 2022-07-25 7.5 HIGH 9.8 CRITICAL
In Python before 3,9,5, the ipaddress library mishandles leading zero characters in the octets of an IP address string. This (in some situations) allows attackers to bypass access control that is based on IP addresses.
CVE-2018-18074 4 Canonical, Opensuse, Python and 1 more 6 Ubuntu Linux, Leap, Requests and 3 more 2022-07-25 5.0 MEDIUM 7.5 HIGH
The Requests package before 2.20.0 for Python sends an HTTP Authorization header to an http URI upon receiving a same-hostname https-to-http redirect, which makes it easier for remote attackers to discover credentials by sniffing the network.
CVE-2019-9636 7 Canonical, Debian, Fedoraproject and 4 more 16 Ubuntu Linux, Debian Linux, Fedora and 13 more 2022-07-25 5.0 MEDIUM 9.8 CRITICAL
Python 2.7.x through 2.7.16 and 3.x through 3.7.2 is affected by: Improper Handling of Unicode Encoding (with an incorrect netloc) during NFKC normalization. The impact is: Information disclosure (credentials, cookies, etc. that are cached against a given hostname). The components are: urllib.parse.urlsplit, urllib.parse.urlparse. The attack vector is: A specially crafted URL could be incorrectly parsed to locate cookies or authentication data and send that information to a different host than when parsed correctly. This is fixed in: v2.7.17, v2.7.17rc1, v2.7.18, v2.7.18rc1; v3.5.10, v3.5.10rc1, v3.5.7, v3.5.8, v3.5.8rc1, v3.5.8rc2, v3.5.9; v3.6.10, v3.6.10rc1, v3.6.11, v3.6.11rc1, v3.6.12, v3.6.9, v3.6.9rc1; v3.7.3, v3.7.3rc1, v3.7.4, v3.7.4rc1, v3.7.4rc2, v3.7.5, v3.7.5rc1, v3.7.6, v3.7.6rc1, v3.7.7, v3.7.7rc1, v3.7.8, v3.7.8rc1, v3.7.9.
CVE-2014-4616 4 Opensuse, Opensuse Project, Python and 1 more 4 Opensuse, Opensuse, Python and 1 more 2022-07-13 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-2021-27923 2 Fedoraproject, Python 2 Fedora, Pillow 2022-07-12 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-2021-27921 2 Fedoraproject, Python 2 Fedora, Pillow 2022-07-12 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-2021-27922 2 Fedoraproject, Python 2 Fedora, Pillow 2022-07-12 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-2015-1283 8 Canonical, Debian, Google and 5 more 13 Ubuntu Linux, Debian Linux, Chrome and 10 more 2022-07-05 6.8 MEDIUM N/A
Multiple integer overflows in the XML_GetBuffer function in Expat through 2.1.0, as used in Google Chrome before 44.0.2403.89 and other products, allow remote attackers to cause a denial of service (heap-based buffer overflow) or possibly have unspecified other impact via crafted XML data, a related issue to CVE-2015-2716.
CVE-2008-5983 3 Canonical, Fedoraproject, Python 3 Ubuntu Linux, Fedora, Python 2022-07-05 6.9 MEDIUM N/A
Untrusted search path vulnerability in the PySys_SetArgv API function in Python 2.6 and earlier, and possibly later versions, prepends an empty string to sys.path when the argv[0] argument does not contain a path separator, which might allow local users to execute arbitrary code via a Trojan horse Python file in the current working directory.
CVE-2018-1000117 2 Microsoft, Python 2 Windows, Python 2022-07-05 7.2 HIGH 6.7 MEDIUM
Python Software Foundation CPython version From 3.2 until 3.6.4 on Windows contains a Buffer Overflow vulnerability in os.symlink() function on Windows that can result in Arbitrary code execution, likely escalation of privilege. This attack appears to be exploitable via a python script that creates a symlink with an attacker controlled name or location. This vulnerability appears to have been fixed in 3.7.0 and 3.6.5.
CVE-2020-15523 3 Microsoft, Netapp, Python 3 Windows, Snapcenter, Python 2022-07-05 6.9 MEDIUM 7.8 HIGH
In Python 3.6 through 3.6.10, 3.7 through 3.7.8, 3.8 through 3.8.4rc1, and 3.9 through 3.9.0b4 on Windows, a Trojan horse python3.dll might be used in cases where CPython is embedded in a native application. This occurs because python3X.dll may use an invalid search path for python3.dll loading (after Py_SetPath has been used). NOTE: this issue CANNOT occur when using python.exe from a standard (non-embedded) Python installation on Windows.
CVE-2008-4864 1 Python 1 Python 2022-07-05 7.5 HIGH N/A
Multiple integer overflows in imageop.c in the imageop module in Python 1.5.2 through 2.5.1 allow context-dependent attackers to break out of the Python VM and execute arbitrary code via large integer values in certain arguments to the crop function, leading to a buffer overflow, a different vulnerability than CVE-2007-4965 and CVE-2008-1679.
CVE-2008-1721 3 Canonical, Debian, Python 3 Ubuntu Linux, Debian Linux, Python 2022-07-05 7.5 HIGH N/A
Integer signedness error in the zlib extension module in Python 2.5.2 and earlier allows remote attackers to execute arbitrary code via a negative signed integer, which triggers insufficient memory allocation and a buffer overflow.
CVE-2008-3142 3 Canonical, Debian, Python 3 Ubuntu Linux, Debian Linux, Python 2022-07-05 7.5 HIGH N/A
Multiple buffer overflows in Python 2.5.2 and earlier on 32bit platforms allow context-dependent attackers to cause a denial of service (crash) or have unspecified other impact via a long string that leads to incorrect memory allocation during Unicode string processing, related to the unicode_resize function and the PyMem_RESIZE macro.
