LTTng-UST is a tracer for Linux user-space applications. The respective versions are 2.13.3 and 2.12.5. Those are bug fix releases correcting a few issues in both stable branches, namely by removing use of non-async-signal-safe functions in the ERR() error-printing macros, and fixing a use-after-free memory read in a list traversal within the statedump code. Specifically in 2.13.3, the bytecode interpreter in LTTng-UST left the context fields byte order uninitialized, thus leading to bogus context field values in the event notification capture feature. Fix this by initializing the byte order. Also specifically in 2.13.3, a too-strict validation of array/sequence field types is relaxed to allow pointer types to be used as integer values. This was allowed prior to 2.13, and this too-strict validation was therefore an instrumentation API regression.
