**Name of the Vulnerable Software and Affected Versions** radare2 version 4.5.0 **Description** The issue is caused by radare2 misparsing signature information in PE files, leading to a segmentation fault in the `r x509 parse algorithmidentifier` function in `libr/util/x509.c`. This occurs due to a malformed object identifier in `IMAGE DIRECTORY ENTRY SECURITY`. **Recommendations** For radare2 version 4.5.0, consider disabling the `r x509 parse algorithmidentifier` function as a temporary workaround until a patch is available. Restrict access to the `libr/util/x509.c` module to minimize the risk of exploitation. Avoid processing PE files with malformed object identifiers in `IMAGE DIRECTORY ENTRY SECURITY` until the issue is resolved.

**Name of the Vulnerable Software and Affected Versions** radare2 version 4.5.0 **Description** The issue is related to the misparsing of DWARF information in executable files, which causes a segmentation fault in the `parse typedef` function in `type dwarf.c`. This occurs due to a malformed `DW AT name` in the `.debug info` section. **Recommendations** For radare2 version 4.5.0, as a temporary workaround, consider disabling the `parse typedef` function in `type dwarf.c` to prevent the segmentation fault until a patch is available. Restrict access to malformed executable files to minimize the risk of exploitation.
