CVE-2018-1000030
https://notcve.org/view.php?id=CVE-2018-1000030
Python 2.7.14 is vulnerable to a Heap-Buffer-Overflow as well as a Heap-Use-After-Free. Python versions prior to 2.7.14 may also be vulnerable and it appears that Python 2.7.17 and prior may also be vulnerable however this has not been confirmed. The vulnerability lies when multiply threads are handling large amounts of data. In both cases there is essentially a race condition that occurs. For the Heap-Buffer-Overflow, Thread 2 is creating the size for a buffer, but Thread1 is already writing to the buffer without knowing how much to write. • https://github.com/tylepr96/CVE-2018-1000030 https://bugs.python.org/issue31530 https://drive.google.com/file/d/1oyR9DAZjZK_SCn3mor6NRAYLJS6ueXaY/view https://security.gentoo.org/glsa/201811-02 https://usn.ubuntu.com/3817-1 https://usn.ubuntu.com/3817-2 https://www.dropbox.com/sh/sj3ee7xv55j36k7/AADwP-YfOYikBMuy32e0uvPFa?dl=0 https://www.oracle.com/security-alerts/cpujan2020.html • CWE-416: Use After Free CWE-787: Out-of-bounds Write •
CVE-2017-17522
https://notcve.org/view.php?id=CVE-2017-17522
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 ** EN DISPUTA ** Lib/webbrowser.py en Python hasta la versión 3.6.3 no valida las cadenas antes de iniciar el programa especificado por la variable de entorno BROWSER. Esto podría permitir que atacantes remotos lleven a cabo ataques de inyección de argumentos mediante una URL manipulada. NOTA: el mantenedor del software indica que es imposible la explotación de esta vulnerabilidad debido a que el código confía en subprocess.Popen y el ajuste por defecto shell=False. • http://www.securityfocus.com/bid/102207 https://bugs.python.org/issue32367 https://security-tracker.debian.org/tracker/CVE-2017-17522 • CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') •
