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.

CVE-2014-4607 LZO vulnerability
Title: LZO vulnerability
Summary: LZO could be made to crash or run programs if it processed specially
crafted data.
Don A. Bailey discovered that LZO incorrectly handled certain input data.
An attacker could use this issue to cause LZO to crash, resulting in a
denial of service, or possibly execute arbitrary code.
Instructions: In general, a standard system update will make all the necessary changes.

CVE-2014-4607 [HIGH] CWE-190 lzo: lzo1x_decompress_safe() integer overflow
lzo: lzo1x_decompress_safe() integer overflow
Integer overflow in the LZO algorithm variant in Oberhumer liblzo2 and lzo-2 before 2.07 on 32-bit platforms might allow remote attackers to execute arbitrary code via a crafted Literal Run.
An integer overflow flaw was found in the way the lzo library decompressed certain archives compressed with the LZO algorithm. An attacker could create a specially crafted LZO-compressed input that, when decompressed by an application using the lzo library, would cause that application to crash or, potentially, execute arbitrary code.

CVE-2014-4607 lzo: lzo1x_decompress_safe() integer overflow
Don A. Bailey of securitymouse.com reports:
Vulnerability Description
An integer overflow may occur when processing any variant of a "literal run"
in the lzo1x_decompress_safe function. Each of these three locations is
subject to an integer overflow when processing zero bytes.
This exposes the code that copies literals to memory corruption.
It should be noted that if the target is 64bit liblzo2, the overflow is still
possible, but impractical. An overflow would require so much input data that
an attack would be infeasible even in modern computers.
This issue is LAZARUS.1
