Buffer Overflow vulnerability in function bitwriter_grow_ in flac before 1.4.0 allows remote attackers to run arbitrary code via crafted input to the encoder.
A flaw was found in the libeconf library. This issue occurs due to a buffer overflow vulnerability in the bitwriter_grow_ function in FLAC that allows remote attackers to run arbitrary code via crafted input to the encoder.
Statement: This CVE marked as important as it can allow authenticated remote users to execute arbitrary code, or allow remote users to cause a denial of service.
flac-1.3.0 in Red Hat Enterprise Linux 7 is not impacted. As it doesn't have the safe_realloc function, so not leaks memory.
Mitigation: Miti

FAQ: Is Azure Linux the only Microsoft product that includes this open-source library and is therefore potentially affected by this vulnerability?
One of the main benefits to our customers who choose to use the Azure Linux distro is the commitment to keep it up to date with the most recent and most secure versions of the open source libraries with which the distro is composed. Microsoft is committed to transparency in this work which is why we began publishing CSAF/VEX in October 2025. See this blog post for more information. If impact to additional products is identified, we will update the CVE to reflect this.
