Title: thttpd tdate_parse() Stack Overflow Vulnerability
Severity: HIGH
Description:
The thttpd web server (versions 1.90a to 2.04) doesn't do proper bounds checking in the date parsing function tdate_parse().
By overflowing a static buffer in tdate_parse() an attacker could remotely execute commands on the thttpd host with the permissions of thttpd.
The buffer overflow occurs when a HTTP GET request is made with an overlong "If-Modified-Since" header(approx. 1300+) characters.
Affected Products:
- Acme thttpd 1.90.0a
- Acme thttpd 1.95.0
- Acme thttpd 2.0.0
- Acme thttpd 2.0.1
- Acme thttpd 2.0.2
- Acme thttpd 2.0.3
- Acme thttpd 2.0.4
