Detailsinfo

A vulnerability was found in llvm llvm-project 15.0.0 (Project Management Software). It has been declared as problematic. Affected by this vulnerability is an unknown part of the component pdflatex.fmt File Handler. The manipulation with an unknown input leads to a null pointer dereference vulnerability. The CWE definition for the vulnerability is CWE-476. A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit. As an impact it is known to affect availability. The summary by CVE is:

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.

The weakness was released 01/27/2024. The advisory is shared at github.com. This vulnerability is known as CVE-2023-46049 since 10/16/2023. Neither technical details nor an exploit are publicly available.
