CVE-2023-27537 – Gentoo Linux Security Advisory 202310-12
https://notcve.org/view.php?id=CVE-2023-27537
30 Mar 2023 — A double free vulnerability exists in libcurl <8.0.0 when sharing HSTS data between separate "handles". This sharing was introduced without considerations for do this sharing across separate threads but there was no indication of this fact in the documentation. Due to missing mutexes or thread locks, two threads sharing the same HSTS data could end up doing a double-free or use-after-free. Multiple vulnerabilities have been discovered in curl, the worst of which could result in arbitrary code execution. Ver... • https://hackerone.com/reports/1897203 • CWE-415: Double Free •

CVE-2023-27533 – curl: TELNET option IAC injection
https://notcve.org/view.php?id=CVE-2023-27533
21 Mar 2023 — A vulnerability in input validation exists in curl <8.0 during communication using the TELNET protocol may allow an attacker to pass on maliciously crafted user name and "telnet options" during server negotiation. The lack of proper input scrubbing allows an attacker to send content or perform option negotiation without the application's intent. This vulnerability could be exploited if an application allows user input, thereby enabling attackers to execute arbitrary code on the system.

CVE-2023-27538 – curl: SSH connection too eager reuse still
https://notcve.org/view.php?id=CVE-2023-27538
21 Mar 2023 — An authentication bypass vulnerability exists in libcurl prior to v8.0.0 where it reuses a previously established SSH connection despite the fact that an SSH option was modified, which should have prevented reuse. libcurl maintains a pool of previously used connections to reuse them for subsequent transfers if the configurations match. However, two SSH settings were omitted from the configuration check, allowing them to match easily, potentially leading to the reuse of an inappropriate connection.

CVE-2022-40304 – libxml2: dict corruption caused by entity reference cycles
https://notcve.org/view.php?id=CVE-2022-40304
01 Nov 2022 — An issue was discovered in libxml2 before 2.10.3. Certain invalid XML entity definitions can corrupt a hash table key, potentially leading to subsequent logic errors. In one case, a double-free can be provoked. Se descubrió un problema en libxml2 antes de la versión 2.10.3. Ciertas definiciones de entidades XML no válidas pueden dañar la clave de una tabla hash, lo que podría provocar errores lógicos posteriores. • https://packetstorm.news/files/id/169824 • CWE-415: Double Free •

CVE-2022-3602 – X.509 Email Address 4-byte Buffer Overflow
https://notcve.org/view.php?id=CVE-2022-3602
01 Nov 2022 — A buffer overrun can be triggered in X.509 certificate verification, specifically in name constraint checking. Note that this occurs after certificate chain signature verification and requires either a CA to have signed the malicious certificate or for the application to continue certificate verification despite failure to construct a path to a trusted issuer. An attacker can craft a malicious email address to overflow four attacker-controlled bytes on the stack. This buffer overflow could result in a crash... • https://github.com/colmmacc/CVE-2022-3602 • CWE-121: Stack-based Buffer Overflow CWE-787: Out-of-bounds Write •
