golang.org/x/net/idna: golang: golang.org/x/net/idna: Privilege escalation via incorrect Punycode label processing

A flaw was found in golang.org/x/net/idna. ToASCII and ToUnicode incorrectly accept Punycode-encoded labels that decode to an ASCII-only hostname for example, xn--example-.com returns example.com instead of an error. Applications that validate the ASCII form then convert to Unicode may grant acce...

USN-8416-1: Go Networking vulnerability

It was discovered that Go Networking incorrectly handled certain Punycode-encoded labels in the idna package. An attacker could possibly use this issue to bypass hostname-based access restrictions...

DEBIAN-CVE-2026-45409

Internationalized Domain Names in Applications IDNA for Python provides support for Internationalized Domain Names in Applications IDNA and Unicode IDNA Compatibility Processing. In versions prior to 3.15, payloads such as "\u0660" N or "\u30fb" N + "\u6f22" utilize the validcontexto function pri...

Internationalized Domain Names in Applications (IDNA): Specially crafted inputs to idna.encode() can bypass CVE-2024-3651 fix

This is the same issue as CVE-2024-3651, however the original remediation in 2024 was not a complete fix. Payloads such as "\u0660" N or "\u30fb" N + "\u6f22" utilize the validcontexto function prior to length rejection, and for high values of N will take a long time to process. Impact A speciall...

CVE-2022-43551

A vulnerability exists in curl 7.87.0 HSTS check that could be bypassed to trick it to keep using HTTP. Using its HSTS support, curl can be instructed to use HTTPS instead of using an insecure clear-text HTTP step even when HTTP is provided in the URL. However, the HSTS mechanism could be bypasse...

Another HSTS bypass via IDN

curl's HSTS check could be bypassed to trick it to keep using HTTP. Using its HSTS support, curl can be instructed to use HTTPS instead of using an insecure clear-text HTTP step even when HTTP is provided in the URL. The HSTS mechanism could be bypassed if the hostname in the given URL first uses...

The vulnerability of DHCP clients for UNIX-based command-line tools like BusyBox, related to integer overflows in value manipulation, allows attackers to trigger a service failure.

The vulnerability of DHCP clients that use UNIX command-line utilities with BusyBox is related to integer overflows. Exploiting this vulnerability allows an attacker to cause a service failure by using a modified domain name with the RFC1035 encoding...
