Am I affected?
Debian, Ubuntu or Red Hat sometimes backport a fix without changing the upstream version number: such a version reads « to verify », never « affected ».With a domain, we read the version its public headers and pages expose. A distribution build can carry the fix under an older number.
Description
libosmocore through 1.14.1 contains out-of-bounds reads in the GSM 04.80 supplementary-service component parsers in src/gsm/gsm0480.c. This allows a remote attacker to obtain sensitive information.
