An integer overflow in the getnum function in lua_struct.c in Redis before 6.0.3

CVE-2020-14147 7.7 - High - June 15, 2020

An integer overflow in the getnum function in lua_struct.c in Redis before 6.0.3 allows context-dependent attackers with permission to run Lua code in a Redis session to cause a denial of service (memory corruption and application crash) or possibly bypass intended sandbox restrictions via a large number, which triggers a stack-based buffer overflow. NOTE: this issue exists because of a CVE-2015-8080 regression.

CVE-2020-14147 can be explotited with network access, and requires small amount of user privledges. This vulnerability is considered to have a low attack complexity. It has an exploitability score of 3.1 out of four. The potential impact of an exploit of this vulnerability is considered to have no impact on confidentiality and integrity, and a high impact on availability.

Integer Overflow or Wraparound

A heap-buffer overflow vulnerability was found in the Redis hyperloglog data structure versions 3.x before 3.2.13

CVE-2019-10192 7.2 - High - July 11, 2019

A heap-buffer overflow vulnerability was found in the Redis hyperloglog data structure versions 3.x before 3.2.13, 4.x before 4.0.14 and 5.x before 5.0.4. By carefully corrupting a hyperloglog using the SETRANGE command, an attacker could trick Redis interpretation of dense HLL encoding to write up to 3 bytes beyond the end of a heap-allocated buffer.

CVE-2019-10192 is exploitable with network access, and requires user privledges. This vulnerability is considered to have a low attack complexity. It has an exploitability score of 1.2 out of four. The potential impact of an exploit of this vulnerability is considered to be very high.

Memory Corruption

A stack-buffer overflow vulnerability was found in the Redis hyperloglog data structure versions 3.x before 3.2.13

CVE-2019-10193 7.2 - High - July 11, 2019

A stack-buffer overflow vulnerability was found in the Redis hyperloglog data structure versions 3.x before 3.2.13, 4.x before 4.0.14 and 5.x before 5.0.4. By corrupting a hyperloglog using the SETRANGE command, an attacker could cause Redis to perform controlled increments of up to 12 bytes past the end of a stack-allocated buffer.

CVE-2019-10193 can be explotited with network access, and requires user privledges. This vulnerability is considered to have a low attack complexity. It has an exploitability score of 1.2 out of four. The potential impact of an exploit of this vulnerability is considered to be very high.

Memory Corruption

An Integer Overflow issue was discovered in the struct library in the Lua subsystem in Redis before 3.2.12

CVE-2018-11219 9.8 - Critical - June 17, 2018

An Integer Overflow issue was discovered in the struct library in the Lua subsystem in Redis before 3.2.12, 4.x before 4.0.10, and 5.x before 5.0 RC2, leading to a failure of bounds checking.

CVE-2018-11219 can be explotited with network access, and does not require authorization privledges or user interaction. This vulnerability is considered to have a low attack complexity. It has the highest possible exploitability rating (3.9). The potential impact of an exploit of this vulnerability is considered to be critical as this vulneraility has a high impact to the confidentiality, integrity and availability of this component.

Integer Overflow or Wraparound

Memory Corruption was discovered in the cmsgpack library in the Lua subsystem in Redis before 3.2.12, 4.x before 4.0.10, and 5.x before 5.0 RC2

CVE-2018-11218 9.8 - Critical - June 17, 2018

Memory Corruption was discovered in the cmsgpack library in the Lua subsystem in Redis before 3.2.12, 4.x before 4.0.10, and 5.x before 5.0 RC2 because of stack-based buffer overflows.

CVE-2018-11218 is exploitable with network access, and does not require authorization privledges or user interaction. This vulnerability is considered to have a low attack complexity. It has the highest possible exploitability rating (3.9). The potential impact of an exploit of this vulnerability is considered to be critical as this vulneraility has a high impact to the confidentiality, integrity and availability of this component.

Out-of-bounds Write

Buffer overflow in redis-cli of Redis before 4.0.10 and 5.x before 5.0 RC3

CVE-2018-12326 8.4 - High - June 17, 2018

Buffer overflow in redis-cli of Redis before 4.0.10 and 5.x before 5.0 RC3 allows an attacker to achieve code execution and escalate to higher privileges via a crafted command line. NOTE: It is unclear whether there are any common situations in which redis-cli is used with, for example, a -h (aka hostname) argument from an untrusted source.

CVE-2018-12326 is exploitable with local system access, and does not require authorization privledges or user interaction. This vulnerability is considered to have a low attack complexity. It has an exploitability score of 2.5 out of four. The potential impact of an exploit of this vulnerability is considered to be very high.

Memory Corruption

Type confusion in the xgroupCommand function in t_stream.c in redis-server in Redis before 5.0

CVE-2018-12453 7.5 - High - June 16, 2018

Type confusion in the xgroupCommand function in t_stream.c in redis-server in Redis before 5.0 allows remote attackers to cause denial-of-service via an XGROUP command in which the key is not a stream.

CVE-2018-12453 can be explotited with network access, and does not require authorization privledges or user interaction. This vulnerability is considered to have a low attack complexity. It has the highest possible exploitability rating (3.9). The potential impact of an exploit of this vulnerability is considered to have no impact on confidentiality and integrity, and a high impact on availability.

Incorrect Type Conversion or Cast

The clusterLoadConfig function in cluster.c in Redis 4.0.2

CVE-2017-15047 9.8 - Critical - October 06, 2017

The clusterLoadConfig function in cluster.c in Redis 4.0.2 allows attackers to cause a denial of service (out-of-bounds array index and application crash) or possibly have unspecified other impact by leveraging "limited access to the machine."

CVE-2017-15047 can be explotited with network access, and does not require authorization privledges or user interaction. This vulnerability is considered to have a low attack complexity. It has the highest possible exploitability rating (3.9). The potential impact of an exploit of this vulnerability is considered to be critical as this vulneraility has a high impact to the confidentiality, integrity and availability of this component.
