CVSS: 7.5EPSS: 0%CPEs: 12EXPL: 0CVE-2021-41099 – Integer overflow issue with strings in Redis
https://notcve.org/view.php?id=CVE-2021-41099
Redis is an open source, in-memory database that persists on disk. An integer overflow bug in the underlying string library can be used to corrupt the heap and potentially result with denial of service or remote code execution. The vulnerability involves changing the default proto-max-bulk-len configuration parameter to a very large value and constructing specially crafted network payloads or commands. The problem is fixed in Redis versions 6.2.6, 6.0.16 and 5.0.14. An additional workaround to mitigate the problem without patching the redis-server executable is to prevent users from modifying the proto-max-bulk-len configuration parameter. • https://github.com/redis/redis/commit/c6ad876774f3cc11e32681ea02a2eead00f2c521 https://github.com/redis/redis/security/advisories/GHSA-j3cr-9h5g-6cph https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/HTYQ5ZF37HNGTZWVNJD3VXP7I6MEEF42 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/VL5KXFN3ATM7IIM7Q4O4PWTSRGZ5744Z https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/WR5WKJWXD4D6S3DJCZ56V74ESLTDQRAB https://security.gentoo.org/gls • CWE-190: Integer Overflow or Wraparound CWE-680: Integer Overflow to Buffer Overflow CWE-787: Out-of-bounds Write •
CVSS: 9.0EPSS: 0%CPEs: 13EXPL: 0CVE-2021-32762 – Integer overflow that can lead to heap overflow in redis-cli, redis-sentinel on some platforms
https://notcve.org/view.php?id=CVE-2021-32762
Redis is an open source, in-memory database that persists on disk. The redis-cli command line tool and redis-sentinel service may be vulnerable to integer overflow when parsing specially crafted large multi-bulk network replies. This is a result of a vulnerability in the underlying hiredis library which does not perform an overflow check before calling the calloc() heap allocation function. This issue only impacts systems with heap allocators that do not perform their own overflow checks. Most modern systems do and are therefore not likely to be affected. • https://github.com/redis/redis/commit/0215324a66af949be39b34be2d55143232c1cb71 https://github.com/redis/redis/security/advisories/GHSA-833w-8v3m-8wwr https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/HTYQ5ZF37HNGTZWVNJD3VXP7I6MEEF42 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/VL5KXFN3ATM7IIM7Q4O4PWTSRGZ5744Z https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/WR5WKJWXD4D6S3DJCZ56V74ESLTDQRAB https://security.gentoo.org/gls • CWE-190: Integer Overflow or Wraparound CWE-680: Integer Overflow to Buffer Overflow •
CVSS: 7.5EPSS: 0%CPEs: 13EXPL: 0CVE-2021-32687 – Integer overflow issue with intsets in Redis
https://notcve.org/view.php?id=CVE-2021-32687
Redis is an open source, in-memory database that persists on disk. An integer overflow bug affecting all versions of Redis can be exploited to corrupt the heap and potentially be used to leak arbitrary contents of the heap or trigger remote code execution. The vulnerability involves changing the default set-max-intset-entries configuration parameter to a very large value and constructing specially crafted commands to manipulate sets. The problem is fixed in Redis versions 6.2.6, 6.0.16 and 5.0.14. An additional workaround to mitigate the problem without patching the redis-server executable is to prevent users from modifying the set-max-intset-entries configuration parameter. • https://github.com/redis/redis/commit/a30d367a71b7017581cf1ca104242a3c644dec0f https://github.com/redis/redis/security/advisories/GHSA-m3mf-8x9w-r27q https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/HTYQ5ZF37HNGTZWVNJD3VXP7I6MEEF42 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/VL5KXFN3ATM7IIM7Q4O4PWTSRGZ5744Z https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/WR5WKJWXD4D6S3DJCZ56V74ESLTDQRAB https://security.gentoo.org/gls • CWE-190: Integer Overflow or Wraparound CWE-680: Integer Overflow to Buffer Overflow CWE-787: Out-of-bounds Write •
CVSS: 7.5EPSS: 0%CPEs: 13EXPL: 0CVE-2021-32675 – DoS vulnerability in Redis
https://notcve.org/view.php?id=CVE-2021-32675
Redis is an open source, in-memory database that persists on disk. When parsing an incoming Redis Standard Protocol (RESP) request, Redis allocates memory according to user-specified values which determine the number of elements (in the multi-bulk header) and size of each element (in the bulk header). An attacker delivering specially crafted requests over multiple connections can cause the server to allocate significant amount of memory. Because the same parsing mechanism is used to handle authentication requests, this vulnerability can also be exploited by unauthenticated users. The problem is fixed in Redis versions 6.2.6, 6.0.16 and 5.0.14. • https://github.com/redis/redis/commit/5674b0057ff2903d43eaff802017eddf37c360f8 https://github.com/redis/redis/security/advisories/GHSA-f6pw-v9gw-v64p https://lists.apache.org/thread.html/ra603ff6e04549d7f290f61f9b11e2d2e4dba693b05ff053f4ec6bc47%40%3Cnotifications.geode.apache.org%3E https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/HTYQ5ZF37HNGTZWVNJD3VXP7I6MEEF42 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/VL5KXFN3ATM7IIM7Q4O4PWTSRGZ5744Z https://lists.fedoraproject.org • CWE-770: Allocation of Resources Without Limits or Throttling •
CVSS: 5.3EPSS: 0%CPEs: 15EXPL: 0CVE-2021-32672 – Vulnerability in Lua Debugger in Redis
https://notcve.org/view.php?id=CVE-2021-32672
Redis is an open source, in-memory database that persists on disk. When using the Redis Lua Debugger, users can send malformed requests that cause the debugger’s protocol parser to read data beyond the actual buffer. This issue affects all versions of Redis with Lua debugging support (3.2 or newer). The problem is fixed in versions 6.2.6, 6.0.16 and 5.0.14.
