CVE-2016-9939 (opens in a new tab)How to fix?
Upgrade SLES:15.2 libcryptopp5_6_5 to version 5.6.5-1.6.1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream libcryptopp5_6_5 package and not the libcryptopp5_6_5 package as distributed by SLES.
See How to fix? for SLES:15.2 relevant fixed versions and status.
Crypto++ (aka cryptopp and libcrypto++) 5.6.4 contained a bug in its ASN.1 BER decoding routine. The library will allocate a memory block based on the length field of the ASN.1 object. If there is not enough content octets in the ASN.1 object, then the function will fail and the memory block will be zeroed even if its unused. There is a noticeable delay during the wipe for a large allocation.
