Vulnerability Title
libvips: Integer overflow leading to heap buffer overflow leading to possible attacker-controlled mmap-resident write
Vulnerability Description
libvips is a fast image processing library with low memory needs. Prior to version 8.18.3, a crafted many-band TIFF processed through VipsForeignLoadTiff can evade scanline validation in libvips/iofuncs/image.c and cause an integer overflow in vips_image_sanity. The resulting buffer-region calculation can access attacker-controlled negative offsets in mmap-resident allocations, allowing reads or writes of other image data, possible data disclosure through uncompressed .v output, and likely process crashes. Remote code execution has not been demonstrated but cannot be ruled out. This issue is fixed in version 8.18.3.

堆缓冲区溢出
Vulnerability Title
libvips 缓冲区错误漏洞
Vulnerability Description
libvips是libvips团队开源的一款图像处理库。 libvips 8.18.3之前版本存在安全漏洞,该漏洞源于特制的多波段TIFF文件通过VipsForeignLoadTiff处理时可绕过扫描线验证,导致整数溢出,使缓冲区区域计算能够访问攻击者控制的负偏移,可能造成其他图像数据的读写、数据泄露及进程崩溃。
