Why Curl is Facing Security Vulnerability Issues

🔒Curl is currently facing security vulnerability issues due to security breaches and attacks.

💣One specific vulnerability is related to the usage of stir copy function in the websocket handling code of the library, which can lead to a buffer overflow.

🔄It is recommended to replace stir copy with a safer alternative, stir end copy, and specify the maximum length to copy.

🔐Using stir and copy ensures that only a specified number of characters up to the buffer size minus one are copied, preventing buffer overflows.

🤔Properly checking the length of input and using safer functions can improve the security of Curl and mitigate potential security risks.
