CVE-2023-46049

一、漏洞信息
漏洞编号：CVE-2023-46049
漏洞归属组件：llvm
漏洞归属的版本：10.0.1,11.0.0,12.0.1,13.0.1,15.0.7,7.0.0
CVSS V2.0分值：
BaseScore：0.0 Low
Vector：CVSS：2.0/
漏洞简述：
LLVM 15.0.0 has a NULL pointer dereference in the parseOneMetadata() function via a crafted pdflatex.fmt file (or perhaps a crafted .o file) to llvm-lto. NOTE: this is disputed because the relationship between pdflatex.fmt and any LLVM language front end is not explained, and because a crash of the llvm-lto application should be categorized as a usability problem.
