version 1.0.28 Which version of libsndfile made this crash. Actually, I didn't get crash in version "libsndfile-1.0.28". Could u please explain this? Ref: https://nvd.nist.gov/vuln/detail/CVE-2018-19758 Thanks in advance. I downloaded the version from this Github resource as follow. https://github.com/erikd/libsndfile/releases (1.0.28) I got the crash now and Sry for the noise in the channel. Thanks The Red Hat Enterprise Linux 7 life cycle has entered Maintenance Support Phase, which means that only qualified Critical and Important Security errata advisories (RHSAs) and some Urgent Priority Bug Fix errata advisories (RHBAs) will be released as they become available. Unfortunately, this issue was not selected to be included in Red Hat Enterprise Linux 7. We will now close this issue. We recommend moving the request to Red Hat Enterprise Linux 8 if applicable.
