Description

Updated radare2 packages fix security vulnerabilities Updated radare2 packages fix security vulnerabilities: In radare2 through 3.5.1, there is a heap-based buffer over-read in the r_egg_lang_parsechar function of egg_lang.c. This allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact because of missing length validation in libr/egg/egg.c (CVE-2019-12790). In radare2 through 3.5.1, the rcc_context function of libr/egg/egg_lang.c mishandles changing context. This allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact (invalid memory access in r_egg_lang_parsechar; invalid free in rcc_pusharg) (CVE-2019-12802). In radare2 through 3.5.1, cmd_mount in libr/core/cmd_mount.c has a double free for the ms command (CVE-2019-12865). By using a crafted executable file, it's possible to execute arbitrary shell commands with the permissions of the victim. This vulnerability is due to improper handling of symbol names embedded in executables (CVE-2019-14745). The radare2 package has been updated to version 3.9.0, fixing these issues and other bugs. Also, the radare2-cutter package has been updated to version 1.9.0.
