Vulnerability Title
OpenEXR: Unhandled assert abort in HTJ2K decoder via crafted QCD marker (DoS)
Vulnerability Description
OpenEXR is the reference implementation and specification for the EXR image format, widely used in the motion picture industry. In versions 3.4.0 through 3.4.12, a crafted HTJ2K-compressed EXR file causes an unconditional process abort in any application that calls exr_start_read() on untrusted input, resulting in denial of service. The crash is triggered by a QCD marker whose lower five bits are zero, which OpenEXR passes into the vendored OpenJPH library while constructing the codestream and evaluating its quantization delta parameters. OpenJPH uses an assertion rather than a recoverable error to validate those bits, so any invalid value calls abort() directly and cannot be intercepted by surrounding error handling, a problem compounded by OpenEXR wrapping only its internal HT header parser in error handling while leaving the later codestream read and construction calls unprotected. This issue has been resolved in version 3.4.13.

Academy Software Foundation OpenEXR 异常处理不当漏洞
Vulnerability Description
Academy Software Foundation OpenEXR是美国Academy Software Foundation基金会开源的一种高动态范围图像(HDR)文件格式的开放标准。 Academy Software Foundation OpenEXR 3.4.0至3.4.13之前版本存在异常处理不当漏洞,该漏洞源于QCD标记低五位为零时,OpenEXR将其传递给OpenJPH库,OpenJPH使用断言验证非法值并直接调用abort(),可能导致任何调用exr_start_read()处理不可信
