| CVE-2025-6170 | Low | 0.09 | 2.5 | 0.00 | Jun 16, 2025 | A flaw was found in the interactive shell of the xmllint command-line tool, used for parsing XML files. When a user inputs an overly long command, the program does not check the input size properly, which can cause it to crash. This issue might allow attackers to run harmful… | ||

| CVE-2022-40303 | Hig | 0.02 | 7.5 | 0.23 | Nov 23, 2022 | An issue was discovered in libxml2 before 2.10.3. When parsing a multi-gigabyte XML document with the XML_PARSE_HUGE parser option enabled, several integer counters can overflow. This results in an attempt to access an array at a negative 2GB offset, typically leading to a… | ||
| CVE-2022-40304 | Hig | 0.01 | 7.8 | 0.07 | Nov 23, 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. | ||
| CVE-2021-3517 | Hig | 0.01 | 8.6 | 0.08 | May 19, 2021 | There is a flaw in the xml entity encoding functionality of libxml2 in versions before 2.9.11. An attacker who is able to supply a crafted file to be processed by an application linked with the affected functionality of libxml2 could trigger an out-of-bounds read. The most… | ||
