Heap Buffer Overflow

curl is vulnerable to Heap Buffer Overflow. The vulnerability is due to the SOCKS5 proxy handshake. If the hostname is longer then 255 bytes, curl switches to local name resolution, and passes the resolved address to the proxy. If the SOCKS5 handshake is slow, the long hostname is directly copied...

USN-6429-1: curl vulnerabilities

Jay Satiro discovered that curl incorrectly handled hostnames when using a SOCKS5 proxy. In environments where curl is configured to use a SOCKS5 proxy, a remote attacker could possibly use this issue to execute arbitrary code. This issue only affected Ubuntu 22.04 LTS, and Ubuntu 23.04...

SOCKS5 heap buffer overflow

This flaw makes curl overflow a heap based buffer in the SOCKS5 proxy handshake. When curl is asked to pass along the hostname to the SOCKS5 proxy to allow that to resolve the address instead of it getting done by curl itself, the maximum length that hostname can be is 255 bytes. If the hostname ...

cookie injection with none file

This flaw allows an attacker to intentionally inject cookies into a running program using libcurl, if the specific series of conditions are met. libcurl performs transfers. In its API, an application creates "easy handles" that are the individual handles for single transfers. libcurl provides a...

CVE-2023-38545

A heap-based buffer overflow flaw was found in the SOCKS5 proxy handshake in the Curl package. If Curl is unable to resolve the address itself, it passes the hostname to the SOCKS5 proxy. However, the maximum length of the hostname that can be passed is 255 bytes. If the hostname is longer, then...
