Vulnerability Description
An issue in fetch_jpg() in xdrv_10_scripter.ino in Tasmota through 15.3.0.3 allows a remote attacker to cause heap buffer overflow. The Content-Length from a JPEG stream is stored in a uint16_t variable; values above 65535 wrap around, causing allocation of a smaller buffer than the data actually read.

Tasmota 安全漏洞
Source: CNNVD (China National Vulnerability Database)
Vulnerability Description
Tasmota是Theo Arends个人开发者的一个物联网设备固件与自动化控制平台。 Tasmota 15.3.0.3及之前版本存在安全漏洞，该漏洞源于xdrv_10_scripter.ino中的fetch_jpg()函数将JPEG流的Content-Length存储在uint16_t变量中，值超过65535时发生环绕，导致分配比实际读取数据更小的缓冲区，从而造成堆缓冲区溢出，可能允许远程攻击者利用此漏洞。
