According to the versions of the llvm packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :
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.(CVE-2023-46049)
Tenable has extracted the preceding description block directly from the EulerOS llvm security advisory.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
