Vulnerability Title
libvips: A well-crafted PPM image processed via a custom source could lead to possible heap buffer write overflow
Vulnerability Description
libvips is a fast image processing library with low memory needs. Prior to version 8.18.3, applications that define unusual custom libvips sources and use them to process untrusted uncompressed PPM images can trigger a max/min error in vips_source_read_to_memory in libvips/iofuncs/source.c. The function uses VIPS_MAX instead of VIPS_MIN when selecting the remaining read size, allowing up to 4032 bytes to be written beyond the allocated heap buffer and causing memory corruption or a process crash. 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之前版本存在缓冲区错误漏洞,该漏洞源于在vips_source_read_to_memory函数中使用VIPS_MAX而非VIPS_MIN选择剩余读取大小,导致最多4032字节被写入分配的堆缓冲区之外,造成内存损坏或进程崩溃。
