Description Quality Assurance univentionstaff 2019-12-18 09:39:01 CET
New Debian ruby2.3 2.3.3-1+deb9u7 fixes:
This update addresses the following issues:
* Ruby through 2.4.7, 2.5.x through 2.5.6, and 2.6.x through 2.6.4 mishandles  path checking within File.fnmatch functions. (CVE-2019-15845)
* regular expression denial of service vulnerability of WEBrick's Digest  access authentication (CVE-2019-16201)
* Ruby through 2.4.7, 2.5.x through 2.5.6, and 2.6.x through 2.6.4 allows  HTTP Response Splitting. If a program using WEBrick inserts untrusted input  into the response header, an attacker can exploit it to insert a newline  character to split a header, and inject malicious content to deceive  clients. NOTE: this issue exists because of an incomplete fix for  CVE-2017-17742, which addressed the CRLF vector, but did not address an  isolated CR or an isolated LF. (CVE-2019-16254)
* Ruby through 2.4.7, 2.5.x through 2.5.6, and 2.6.x through 2.6.4 allows  code injection if the first argument (aka the "command" argument) to  Shell#[] or Shell#test in lib/shell.rb is untrusted data. An attacker can  exploit this to call an arbitrary Ruby method. (CVE-2019-16255)
