Synopsis

The remote openSUSE host is missing a security update.

Description

This update for redis fixes the following issues :

redis 6.0.13

- CVE-2021-29477: Integer overflow in STRALGO LCS command (boo#1185729)

- CVE-2021-29478: Integer overflow in COPY command for large intsets (boo#1185730)

- Cluster: Skip unnecessary check which may prevent failure detection

- Fix performance regression in BRPOP on Redis 6.0

- Fix edge-case when a module client is unblocked

redis 6.0.12 :

- Fix compilation error on non-glibc systems if jemalloc is not used

redis 6.0.11 :

- CVE-2021-21309: Avoid 32-bit overflows when proto-max-bulk-len is set high (boo#1182657)

- Fix handling of threaded IO and CLIENT PAUSE (failover), could lead to data loss or a crash

- Fix the selection of a random element from large hash tables

- Fix broken protocol in client tracking tracking-redir-broken message

- XINFO able to access expired keys on a replica

- Fix broken protocol in redis-benchmark when used with -a or --dbnum

- Avoid assertions (on older kernels) when testing arm64 CoW bug

- CONFIG REWRITE should honor umask settings

- Fix firstkey,lastkey,step in COMMAND command for some commands

- RM_ZsetRem: Delete key if empty, the bug could leave empty zset keys

redis 6.0.10 :

Command behavior changes :

- SWAPDB invalidates WATCHed keys (#8239)

- SORT command behaves differently when used on a writable replica (#8283)

- EXISTS should not alter LRU (#8016) In Redis 5.0 and 6.0 it would have touched the LRU/LFU of the key.

- OBJECT should not reveal logically expired keys (#8016) Will now behave the same TYPE or any other non-DEBUG command.

- GEORADIUS[BYMEMBER] can fail with -OOM if Redis is over the memory limit (#8107)

Other behavior changes :

- Sentinel: Fix missing updates to the config file after SENTINEL SET command (#8229)

- CONFIG REWRITE is atomic and safer, but requires write access to the config file's folder (#7824, #8051) This change was already present in 6.0.9, but was missing from the release notes.

Bug fixes with compatibility implications (bugs introduced in Redis 6.0) :

- Fix RDB CRC64 checksum on big-endian systems (#8270) If you're using big-endian please consider the compatibility implications with RESTORE, replication and persistence.

- Fix wrong order of key/value in Lua's map response (#8266) If your scripts use redis.setresp() or return a map (new in Redis 6.0), please consider the implications.

Bug fixes :

- Fix an issue where a forked process deletes the parent's pidfile (#8231)

- Fix crashes when enabling io-threads-do-reads (#8230)

- Fix a crash in redis-cli after executing cluster backup (#8267)

- Handle output buffer limits for module blocked clients (#8141) Could result in a module sending reply to a blocked client to go beyond the limit.

- Fix setproctitle related crashes. (#8150, #8088) Caused various crashes on startup, mainly on Apple M1 chips or under instrumentation.

- Backup/restore cluster mode keys to slots map for repl-diskless-load=swapdb (#8108) In cluster mode with repl-diskless-load, when loading failed, slot map wouldn't have been restored.

- Fix oom-score-adj-values range, and bug when used in config file (#8046) Enabling setting this in the config file in a line after enabling it, would have been buggy.

- Reset average ttl when empty databases (#8106) Just causing misleading metric in INFO

- Disable rehash when Redis has child process (#8007) This could have caused excessive CoW during BGSAVE, replication or AOFRW.

- Further improved ACL algorithm for picking categories (#7966) Output of ACL GETUSER is now more similar to the one provided by ACL SETUSER.

- Fix bug with module GIL being released prematurely (#8061) Could in theory (and rarely) cause multi-threaded modules to corrupt memory.

- Reduce effect of client tracking causing feedback loop in key eviction (#8100)

- Fix cluster access to unaligned memory (SIGBUS on old ARM) (#7958)

- Fix saving of strings larger than 2GB into RDB files (#8306)

Additional improvements :

- Avoid wasteful transient memory allocation in certain cases (#8286, #5954)

Platform / toolchain support related improvements :

- Fix crash log registers output on ARM. (#8020)

- Add a check for an ARM64 Linux kernel bug (#8224) Due to the potential severity of this issue, Redis will print log warning on startup.

- Raspberry build fix. (#8095)

New configuration options :

- oom-score-adj-values config can now take absolute values (besides relative ones) (#8046)

Module related fixes :

- Moved RMAPI_FUNC_SUPPORTED so that it's usable (#8037)

- Improve timer accuracy (#7987)

- Allow '\0' inside of result of RM_CreateStringPrintf (#6260)

redis 6.0.9 :

- potential heap overflow when using a heap allocator other than jemalloc or glibc's malloc. Does not affect the openSUSE package - boo#1178205

- Memory reporting of clients argv

- Add redis-cli control on raw format line delimiter

- Add redis-cli support for rediss:// -u prefix

- WATCH no longer ignores keys which have expired for MULTI/EXEC

- Correct OBJECT ENCODING response for stream type

- Allow blocked XREAD on a cluster replica

- TLS: Do not require CA config if not used

- multiple bug fixes

- Additions to modules API

redis 6.0.8 (jsc#PM-1615, jsc#PM-1622, jsc#PM-1681, jsc#ECO-2417, jsc#ECO-2867, jsc#PM-1547, jsc#CAPS-56, jsc#SLE-11578, jsc#SLE-12821) :

- Show IO threads statistics and status in INFO output

- Add optional tls verification mode (see tls-auth-clients)

redis 6.0.6 :

redis 6.0.5 :

- Fix handling of speical chars in ACL LOAD

- Make Redis Cluster more robust about operation errors that may lead to two clusters to mix together

- Revert the sendfile() implementation of RDB transfer

- Fix TLS certificate loading for chained certificates
