Amazon Linux 2 Security Advisory: ALAS-2019-1247
Advisory Release Date: 2019-07-18 17:40 Pacific
Advisory Updated Date: 2019-07-22 16:35 Pacific
Severity:
Important
Issue Overview:
An issue was discovered in urllib2 in Python 2.x and urllib in Python 3.x. CRLF injection is possible if the attacker controls a url parameter, as demonstrated by the first argument to urllib.request.urlopen with \r\n (specifically in the path component of a URL that lacks a ? character) followed by an HTTP header or a Redis command. This is similar to the CVE-2019-9740 query string issue. (CVE-2019-9947, CVE-2019-9740)
Affected Packages:
python3
Note:
This advisory is applicable to Amazon Linux 2 (AL2) Core repository. Visit this FAQ section for the difference between AL2 Core and AL2 Extras advisories.
