CVSS: 7.1EPSS: 0%CPEs: 7EXPL: 1CVE-2023-34241 – CUPS vulnerable to use-after-free in cupsdAcceptClient()
https://notcve.org/view.php?id=CVE-2023-34241
OpenPrinting CUPS is a standards-based, open source printing system for Linux and other Unix-like operating systems. Starting in version 2.0.0 and prior to version 2.4.6, CUPS logs data of free memory to the logging service AFTER the connection has been closed, when it should have logged the data right before. This is a use-after-free bug that impacts the entire cupsd process. The exact cause of this issue is the function `httpClose(con->http)` being called in `scheduler/client.c`. The problem is that httpClose always, provided its argument is not null, frees the pointer at the end of the call, only for cupsdLogClient to pass the pointer to httpGetHostname. This issue happens in function `cupsdAcceptClient` if LogLevel is warn or higher and in two scenarios: there is a double-lookup for the IP Address (HostNameLookups Double is set in `cupsd.conf`) which fails to resolve, or if CUPS is compiled with TCP wrappers and the connection is refused by rules from `/etc/hosts.allow` and `/etc/hosts.deny`. Version 2.4.6 has a patch for this issue. • http://www.openwall.com/lists/oss-security/2023/06/23/10 http://www.openwall.com/lists/oss-security/2023/06/26/1 https://github.com/OpenPrinting/cups/commit/9809947a959e18409dcf562a3466ef246cb90cb2 https://github.com/OpenPrinting/cups/releases/tag/v2.4.6 https://github.com/OpenPrinting/cups/security/advisories/GHSA-qjgh-5hcq-5f25 https://lists.debian.org/debian-lts-announce/2023/06/msg00038.html https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/7I7DWGYGE • CWE-416: Use After Free •

https://notcve.org/view.php?id=CVE-2023-2953
A vulnerability was found in openldap. This security flaw causes a null pointer dereference in ber_memalloc_x() function. A vulnerability was found in OpenLDAP, in ber_memalloc_x() function, leading to a null pointer dereference. This flaw can result in reduced system memory and cause LDAP authentication failures. The impact is primarily a disruption in authentication processes, which may hinder user access or service operations relying on LDAP for authentication. • http://seclists.org/fulldisclosure/2023/Jul/47 http://seclists.org/fulldisclosure/2023/Jul/48 http://seclists.org/fulldisclosure/2023/Jul/52 https://access.redhat.com/security/cve/CVE-2023-2953 https://bugs.openldap.org/show_bug.cgi?id=9904 https://security.netapp.com/advisory/ntap-20230703-0005 https://support.apple.com/kb/HT213843 https://support.apple.com/kb/HT213844 https://support.apple.com/kb/HT213845 https://bugzilla.redhat.com/show_bug.cgi?id=2210651 • CWE-476: NULL Pointer Dereference •
CVSS: 7.5EPSS: 0%CPEs: 14EXPL: 1CVE-2023-28319 – curl: use after free in SSH sha256 fingerprint check
https://notcve.org/view.php?id=CVE-2023-28319
A use after free vulnerability exists in curl <v8.1.0 in the way libcurl offers a feature to verify an SSH server's public key using a SHA 256 hash. When this check fails, libcurl would free the memory for the fingerprint before it returns an error message containing the (now freed) hash. This flaw risks inserting sensitive heap-based data into the error message that might be shown to users or otherwise get leaked and revealed. A use-after-free flaw was found in the Curl package. This flaw risks inserting sensitive heap-based data into the error message that users might see or is otherwise leaked and revealed. • http://seclists.org/fulldisclosure/2023/Jul/47 http://seclists.org/fulldisclosure/2023/Jul/48 http://seclists.org/fulldisclosure/2023/Jul/52 https://hackerone.com/reports/1913733 https://security.gentoo.org/glsa/202310-12 https://security.netapp.com/advisory/ntap-20230609-0009 https://support.apple.com/kb/HT213843 https://support.apple.com/kb/HT213844 https://support.apple.com/kb/HT213845 https://access.redhat.com/security/cve/CVE-2023-28319 https://bugzilla.redhat.com/ • CWE-416: Use After Free •
CVSS: 3.7EPSS: 0%CPEs: 16EXPL: 1CVE-2023-28322 – curl: more POST-after-PUT confusion
https://notcve.org/view.php?id=CVE-2023-28322
An information disclosure vulnerability exists in curl <v8.1.0 when doing HTTP(S) transfers, libcurl might erroneously use the read callback (`CURLOPT_READFUNCTION`) to ask for data to send, even when the `CURLOPT_POSTFIELDS` option has been set, if the same handle previously wasused to issue a `PUT` request which used that callback. This flaw may surprise the application and cause it to misbehave and either send off the wrong data or use memory after free or similar in the second transfer. The problem exists in the logic for a reused handle when it is (expected to be) changed from a PUT to a POST. A use-after-free flaw was found in the Curl package. This issue may lead to unintended information disclosure by the application. • http://seclists.org/fulldisclosure/2023/Jul/47 http://seclists.org/fulldisclosure/2023/Jul/48 http://seclists.org/fulldisclosure/2023/Jul/52 https://hackerone.com/reports/1954658 https://lists.debian.org/debian-lts-announce/2023/12/msg00015.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/F4I75RDGX5ULSSCBE5BF3P5I5SFO7ULQ https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/Z2LIWHWKOVH24COGGBCVOWDXXIUPKOMK https://security.gentoo • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-440: Expected Behavior Violation •
