Description John Helmert III archtester Gentoo Infrastructure gentoo-dev Security 2020-08-03 19:11:38 UTC 
CVE-2020-16269:

radare2 4.5.0 misparses DWARF information in executable files, causing a segmentation fault in parse_typedef in type_dwarf.c via a malformed DW_AT_name in the .debug_info section.



Looks like a fix is set for the 4.6.0 milestone. No patch yet.

Patch was included in 4.5.1, and tree is clean. All done!
