NVD Description

Note: Versions mentioned in the description apply only to the upstream amazon-cloudwatch-agent package and not the amazon-cloudwatch-agent package as distributed by SLES. See How to fix? for SLES:15.4 relevant fixed versions and status.

compress provides various compression algorithms. Prior to version 1.18.7, a signed integer overflow vulnerability in s2.NewDict() allows an attacker to bypass repeat index validation by supplying a dictionary with a uvarint-encoded repeat value exceeding MaxInt64. When Dict.Encode() is subsequently called, the overflowed negative repeat value causes an out-of-bounds memory access via unsafe.Pointer arithmetic, crashing the process with SIGSEGV. This issue has been patched in version 1.18.7.
