CVE-2019-19204

An out-of-bounds read vulnerability was found in Oniguruma in the way it handled regular expression quantifiers. A remote attacker could abuse this flaw by providing a malformed regular expression that, when processed by an application linked to Oniguruma, could possibly crash the application,...

CVE-2019-19203

An out-of-bounds read vulnerability was found in the way Oniguruma handled regular expressions with GB18030 character encoding. A UChar pointer is dereferenced without checking if it passed the end of the matched string, leading to a heap-based buffer over-read. A remote attacker could abuse this...

Exploit for Uncontrolled Resource Consumption in Agendaless Waitress

Waitress 1.4.2 ReDoS - CVE-2020-5236 Waitress version 1.4.2...

Denial Of Service (DoS)

waitress is vulnerable to denial of service DoS. The vulnerability exists as catastrophic backtracking could occur through the use of a greedy regular expression that does not conform to RFC7230, and subsequently used to validate HTTP headers...

CVE-2020-5236

Waitress version 1.4.2 allows a DOS attack When waitress receives a header that contains invalid characters. When a header like "Bad-header: xxxxxxxxxxxxxxx\x10" is received, it will cause the regular expression engine to catastrophically backtrack causing the process to use 100% CPU time and...

GHSA-73M2-3PWG-5FGC Catastrophic backtracking in regex allows Denial of Service in Waitress

Impact When waitress receives a header that contains invalid characters it will cause the regular expression engine to catastrophically backtrack causing the process to use 100% CPU time and blocking any other interactions. This would allow an attacker to send a single request with an invalid...

CVE-2020-5236

CVE-2020-5236 affects the Python WSGI server waitress. A flaw in the regex used to validate incoming HTTP headers allows catastrophic backtracking when headers contain invalid characters (e.g., Bad-header: xxxxxxxxxxxxxxx\x10), causing the server to hit 100% CPU and deny service. The issue was in...
