Category:	Mageia Linux Local Security Checks
Title:	Mageia: Security Advisory (MGASA-2022-0468)
Summary:	The remote host is missing an update for the 'heimdal' package(s) announced via the MGASA-2022-0468 advisory.
Description:	Summary: The remote host is missing an update for the 'heimdal' package(s) announced via the MGASA-2022-0468 advisory. Vulnerability Insight: Isaac Boukris reported that the Heimdal KDC before 7.7.1 does not apply delegation_not_allowed (aka not-delegated) user attributes for S4U2Self. Instead the forwardable flag is set even if the impersonated client has the not-delegated flag set. (CVE-2019-14870) Joseph Sutton discovered that the Heimdal KDC before 7.7.1 does not check for missing missing sname in TGS-REQ (Ticket Granting Server Request) before before dereferencing. An authenticated user could use this flaw to crash the KDC. (CVE-2021-3671) It was discovered that Heimdal is prone to a NULL dereference in acceptors when the initial SPNEGO token has no acceptable mechanisms, which may result in denial of service for a server application that uses the Simple and Protected GSSAPI Negotiation Mechanism (SPNEGO). (CVE-2021-44758) Evgeny Legerov reported that the DES and Triple-DES decryption routines in the Heimdal GSSAPI library before 7.7.1 were prone to buffer overflow on malloc() allocated memory when presented with a maliciously small packet. In addition, the Triple-DES and RC4 (arcfour) decryption routine were prone to non-constant time leaks, which could potentially yield to a leak of secret key material when using these ciphers. (CVE-2022-3437) It was discovered that Heimdal's PKI certificate validation library before 7.7.1 can under some circumstances perform an out-of-bounds memory access when normalizing Unicode, which may result in denial of service. (CVE-2022-41916) Greg Hudson discovered an integer multiplication overflow in the Privilege Attribute Certificate (PAC) parsing routine, which may result in denial of service for Heimdal KDCs and possibly Heimdal servers (e.g., via GSS-API) on 32-bit systems. (CVE-2022-42898) Douglas Bagnall and the Heimdal maintainers independently discovered that Heimdal's ASN.1 compiler before 7.7.1 generates code that allows specially crafted DER encodings of CHOICEs to invoke the wrong free() function on the decoded structure upon decode error, which may result in remote code execution in the Heimdal KDC and possibly the Kerberos client, the X.509 library, and other components as well. (CVE-2022-44640) Affected Software/OS: 'heimdal' package(s) on Mageia 8. Solution: Please install the updated package(s). CVSS Score: 6.4 CVSS Vector: AV:N/AC:L/Au:N/C:P/I:P/A:N
