Red Hat Security Advisory: Red Hat OpenShift Data Foundation 4.15.0 security, enhancement, & bug fix update

Important

A race condition vulnerability was found in rpm. A local unprivileged user could use this flaw to bypass the checks that were introduced in response to CVE-2017-7500 and CVE-2017-7501, potentially gaining root privileges. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.

CWE-367 - Time-of-check Time-of-use (TOCTOU) Race Condition

A symbolic link issue was found in rpm. It occurs when rpm sets the desired permissions and credentials after installing a file. A local unprivileged user could use this flaw to exchange the original file with a symbolic link to a security-critical file and escalate their privileges on the system. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.

CWE-59 - Improper Link Resolution Before File Access ('Link Following')

It was found that the fix for CVE-2017-7500 and CVE-2017-7501 was incomplete: the check was only implemented for the parent directory of the file to be created. A local unprivileged user who owns another ancestor directory could potentially use this flaw to gain root privileges. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.

CWE-59 - Improper Link Resolution Before File Access ('Link Following')

A flaw was found in the HashiCorp Vault. The Vault and Vault Enterprise (“Vault”) LDAP auth method allows unauthenticated users to potentially enumerate valid accounts in the configured LDAP system by observing the response error when querying usernames.

CWE-203 - Observable Discrepancy

A flaw was found in OpenSSL in how it processes key and initialization vector (IV) lengths. This issue can lead to potential truncation or overruns during the initialization of some symmetric ciphers. A truncation in the IV can result in non-uniqueness, which could result in loss of confidentiality for some cipher modes. Both truncations and overruns of the key and the IV will produce incorrect results and could, in some cases, trigger a memory exception.

CWE-325 - Missing Cryptographic Step

A flaw was found in The HashiCorp Vault, which may be susceptible to a denial of service due to an unbounded consumption of memory when handling policy requests. This issue may allow an attacker to trigger policy checks by sending multiple inbound client requests that create a logger that is never removed from memory, leading to excessive memory consumption, causing a denial of service condition.

CWE-401 - Missing Release of Memory after Effective Lifetime

A vulnerability was found that the response times to malformed ciphertexts in RSA-PSK ClientKeyExchange differ from response times of ciphertexts with correct PKCS#1 v1.5 padding.

CWE-203 - Observable Discrepancy

A vulnerability was found in SQLite3. This issue affects the sessionReadRecord function of the ext/session/sqlite3session.c function in the make alltest Handler component. Manipulation may cause a heap-based buffer overflow to occur.

CWE-122 - Heap-based Buffer Overflow
