A vulnerbility was found in OpenSC. This security flaw cause a buffer overrun vulnerability in pkcs15 cardos_have_verifyrc_package. The attacker can supply a smart card package with malformed ASN1 context. The cardos_have_verifyrc_package function scans the ASN1 buffer for 2 tags, where remaining length is wrongly caculated due to moved starting pointer. This leads to possible heap-based buffer oob read. • https://access.redhat.com/security/cve/CVE-2023-2977 https://bugzilla.redhat.com/show_bug.cgi?id=2211088 https://github.com/OpenSC/OpenSC/issues/2785 https://github.com/OpenSC/OpenSC/pull/2787 https://lists.debian.org/debian-lts-announce/2023/06/msg00025.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/FJD4Q4AJSGE5UIJI7OUYZY4HGGCVYQNI https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/LAR54OV6EHA56B4XJF6RNPQ4HJ2ITU66 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-125: Out-of-bounds Read •

https://notcve.org/view.php?id=CVE-2023-2283
A vulnerability was found in libssh, where the authentication check of the connecting client can be bypassed in the`pki_verify_data_signature` function in memory allocation problems. This issue may happen if there is insufficient memory or the memory usage is limited. The problem is caused by the return value `rc,` which is initialized to SSH_ERROR and later rewritten to save the return value of the function call `pki_key_check_hash_compatible.` The value of the variable is not changed between this point and the cryptographic verification. Therefore any error between them calls `goto error` returning SSH_OK. • http://packetstormsecurity.com/files/172861/libssh-0.9.6-0.10.4-pki_verify_data_signature-Authorization-Bypass.html https://access.redhat.com/security/cve/CVE-2023-2283 https://bugzilla.redhat.com/show_bug.cgi?id=2189736 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/27PD44ALQTZXX7K6JAM3BXBUHYA6DFFN https://security.gentoo.org/glsa/202312-05 https://security.netapp.com/advisory/ntap-20240201-0005 https://www.libssh.org/security/advisories/CVE-2023-2283.txt • CWE-287: Improper Authentication •
