### [CVE-2018-12886](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2018-12886) ![](https://img.shields.io/static/v1?label=Product&message=n%2Fa&color=blue) ![](https://img.shields.io/static/v1?label=Version&message=n%2Fa&color=blue) ![](https://img.shields.io/static/v1?label=Vulnerability&message=n%2Fa&color=brighgreen) ### Description stack_protect_prologue in cfgexpand.c and stack_protect_epilogue in function.c in GNU Compiler Collection (GCC) 4.1 through 8 (under certain circumstances) generate instruction sequences when targeting ARM targets that spill the address of the stack protector guard, which allows an attacker to bypass the protection of -fstack-protector, -fstack-protector-all, -fstack-protector-strong, and -fstack-protector-explicit against stack overflow by controlling what the stack canary is compared against. ### POC #### Reference No PoCs from references. #### Github - https://github.com/ARPSyndicate/cvemon - https://github.com/Azure/container-scan - https://github.com/Azure/publish-security-assessments - https://github.com/PajakAlexandre/wik-dps-tp02 - https://github.com/actions-marketplace-validations/Azure_container-scan - https://github.com/actions-marketplace-validations/Azure_publish-security-assessments - https://github.com/actions-marketplace-validations/ajinkya599_container-scan - https://github.com/drjhunter/container-scan - https://github.com/garethr/snykout - https://github.com/lucky-sideburn/secpod_wrap
