Red Hat Enterprise Linux 7 update for git

1) Insufficiently Protected Credentials

EUVDB-ID: #VU27257

Risk: Low

CVSSv4.0: 1.7 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2020-11008

CWE-ID: CWE-522 - Insufficiently Protected Credentials

Exploit availability: No

Description

The vulnerability allows a remote attacker to gain access to sensitive information on the system

The vulnerability exists due to the Git can be tricked into sending private credentials to a host controlled by an attacker. A remote attacker can send a specially crafted URL to "git clone" that will present stored credentials for any host to a host of their choosing.

Note: This vulnerability is similar to the CVE-2020-5260 (SB2020041523). The fix for that bug still left the door open for an exploit where some credential is leaked (but the attacker cannot control which one).

Mitigation

Install updates from vendor's website.
