A vulnerability has been discovered in 3proxy, possibly resulting in a Denial of Service.
| Package | Arch | Vulnerable | Unaffected |
|---|---|---|---|
| net-proxy/3proxy | * | < 0.5.3j | >= 0.5.3j |
3proxy is a really tiny cross-platform proxy servers set, including HTTP, HTTPS, FTP, SOCKS and POP3 support.
3proxy contains a double free vulnerability in the ftpprchild() function, which frees param->hostname and calls the parsehostname() function, which in turn attempts to free param->hostname again.
A remote attacker could send a specially crafted request to the proxy, possibly resulting in a Denial of Service. Under typical configuration, the scope of this vulnerability is limited to the local network.
There is no known workaround at this time.
All 3proxy users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-proxy/3proxy-0.5.3j"
A vulnerability has been discovered in 3proxy allowing for the remote execution of arbitrary code.
| Package | Arch | Vulnerable | Unaffected |
|---|---|---|---|
| net-proxy/3proxy | * | < 0.5.3h | >= 0.5.3h |
3proxy is a multi-protocol proxy, including HTTP/HTTPS/FTP and SOCKS support.
The 3proxy development team reported a buffer overflow in the logurl() function when processing overly long requests.
A remote attacker could send a specially crafted transparent request to the proxy, resulting in the execution of arbitrary code with privileges of the user running 3proxy.
There is no known workaround at this time.
All 3proxy users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-proxy/3proxy-0.5.3h"
