Summary
An issue was discovered in Squid before 5.0.2. A remote attacker can replay a sniffed Digest Authentication nonce to gain access to resources that are otherwise forbidden. This occurs because the attacker can overflow the nonce reference counter (a short integer). Remote code execution may occur if the pooled token credentials are freed (instead of replayed as valid credentials).

Summary
Red Hat Security Advisory: squid:4 security update
Notes
Topic
An update for the squid:4 module is now available for Red Hat Enterprise Linux 8.
Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details
Squid is a high-performance proxy caching server for web clients, supporting FTP, Gopher, and HTTP data objects.
Security Fix(es):
* squid: improper check for new member in ESIExpression::Evaluate allows for stack buffer overflow (CVE-2019-12519)
* squid: improper access restriction upon Digest Authentication nonce replay could lead to remote code execution (CVE-2020-11945)
* squid: parsing of header Proxy-Authentication leads to memory corruption (CVE-2019-12525)
For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Summary
Red Hat Security Advisory: squid:4 security update
Notes
Topic
An update for the squid:4 module is now available for Red Hat Enterprise Linux 8.0 Update Services for SAP Solutions.
Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details
Squid is a high-performance proxy caching server for web clients, supporting FTP, Gopher, and HTTP data objects.
Security Fix(es):
* squid: improper check for new member in ESIExpression::Evaluate allows for stack buffer overflow (CVE-2019-12519)
* squid: improper access restriction upon Digest Authentication nonce replay could lead to remote code execution (CVE-2020-11945)
For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Summary
Red Hat Security Advisory: squid security update
Notes
Topic
An update for squid is now available for Red Hat Enterprise Linux 7.
Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details
Squid is a high-performance proxy caching server for web clients, supporting FTP, Gopher, and HTTP data objects.
Security Fix(es):
* squid: improper check for new member in ESIExpression::Evaluate allows for stack buffer overflow (CVE-2019-12519)
* squid: improper access restriction upon Digest Authentication nonce replay could lead to remote code execution (CVE-2020-11945)
* squid: parsing of header Proxy-Authentication leads to memory corruption (CVE-2019-12525)
For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Summary
Red Hat Security Advisory: squid:4 security update
Notes
Topic
An update for the squid:4 module is now available for Red Hat Enterprise Linux 8.1 Extended Update Support.
Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details
Squid is a high-performance proxy caching server for web clients, supporting FTP, Gopher, and HTTP data objects.
Security Fix(es):
* squid: improper check for new member in ESIExpression::Evaluate allows for stack buffer overflow (CVE-2019-12519)
* squid: improper access restriction upon Digest Authentication nonce replay could lead to remote code execution (CVE-2020-11945)
For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

gsd-2020-11945
Vulnerability from gsd
Modified
2023-12-13 01:22
Details
An issue was discovered in Squid before 5.0.2. A remote attacker can replay a sniffed Digest Authentication nonce to gain access to resources that are otherwise forbidden. This occurs because the attacker can overflow the nonce reference counter (a short integer). Remote code execution may occur if the pooled token credentials are freed (instead of replayed as valid credentials).
