GNU Binutils Buffer Overflow Flaws

Information disclosure and denial-of-service in GNU Binutils' BFD linker (ld) arises from an out-of-bounds heap read when parsing malformed XCOFF object files. A local attacker who convinces a user to link or otherwise process a specially crafted XCOFF file can leak adjacent heap memory (CWE-125) or crash the linking process. Tracked by Red Hat across RHEL 6 through 10 and OpenShift 4; no public exploit is identified and EPSS exploitation probability is negligible (0.01%, 2nd percentile).

Out-of-bounds heap read in the BFD linker (ld) component of GNU Binutils allows information disclosure or an application-level crash when a victim is induced to process a crafted XCOFF object file. Affected across Red Hat Enterprise Linux 6 through 10 (and OpenShift Container Platform 4), exploitation requires user interaction and local file processing - there is no public exploit identified at time of analysis, and the EPSS probability is negligible (0.01%, 2nd percentile).
