"Description": "This update upgrades libxml2 to version 2.9.12-alt1. \nSecurity Fix(es):\n\n * BDU:2020-03623: Уязвимость функций xmlStringLenDecodeEntities библиотеки libxml2, позволяющая нарушителю вызвать отказ в обслуживании\n\n * BDU:2020-04514: Уязвимость компонента xmlschemas.c библиотеки libxml2, позволяющая нарушителю вызвать отказ в обслуживании\n\n * BDU:2021-02772: Уязвимость библиотеки libxml2, связанная с недостаточной проверкой вводимых данных, позволяющая нарушителю, вызвать состояние отказа в обслуживании\n\n * BDU:2021-03429: Уязвимость функции xmlEncodeEntitiesInternal компонента libxml2/entities.c библиотеки Libxml2, связанная с чтением за допустимыми границами буфера данных, позволяющая нарушителю получить доступ к конфиденциальным данным, а также вызвать отказ в обслуживании\n\n * BDU:2021-05268: Уязвимость компонента parser.c библиотеки Libxml2, связанная с ошибками разыменования указателя, позволяющая нарушителю вызвать отказ в обслуживании\n\n * BDU:2021-05274: Уязвимость функционала кодирования xml объектов библиотеки Libxml2, связанная с записью за границами буфера, позволяющая нарушителю получить доступ к конфиденциальным данным, нарушить их целостность, а также вызвать отказ в обслуживании\n\n * BDU:2021-05282: Уязвимость компонента xmllint библиотеки Libxml2, связанная с использованием памяти после её освобождения, позволяющая нарушителю получить доступ к конфиденциальным данным, нарушить их целостность, а также вызвать отказ в обслуживании\n\n * BDU:2021-05283: Уязвимость компонента xinclude.c библиотеки Libxml2, связанная с использованием памяти после её освобождения, позволяющая нарушителю получить доступ к конфиденциальным данным, нарушить их целостность, а также вызвать отказ в обслуживании\n\n * CVE-2016-3709: Possible cross-site scripting vulnerability in libxml after commit 960f0e2.\n\n * CVE-2019-20388: xmlSchemaPreRun in xmlschemas.c in libxml2 2.9.10 allows an xmlSchemaValidateStream memory leak.\n\n * CVE-2020-24977: GNOME project libxml2 v2.9.10 has a global buffer over-read vulnerability in xmlEncodeEntitiesInternal at libxml2/entities.c. The issue has been fixed in commit 50f06b3e.\n\n * CVE-2020-7595: xmlStringLenDecodeEntities in parser.c in libxml2 2.9.10 has an infinite loop in a certain end-of-file situation.\n\n * CVE-2021-3516: There's a flaw in libxml2's xmllint in versions before 2.9.11. An attacker who is able to submit a crafted file to be processed by xmllint could trigger a use-after-free. The greatest impact of this flaw is to confidentiality, integrity, and availability.\n\n * CVE-2021-3517: 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 likely impact of this flaw is to application availability, with some potential impact to confidentiality and integrity if an attacker is able to use memory information to further exploit the application.\n\n * CVE-2021-3518: There's a flaw in libxml2 in versions before 2.9.11. An attacker who is able to submit a crafted file to be processed by an application linked with libxml2 could trigger a use-after-free. The greatest impact from this flaw is to confidentiality, integrity, and availability.\n\n * CVE-2021-3537: A vulnerability found in libxml2 in versions before 2.9.11 shows that it did not propagate errors while parsing XML mixed content, causing a NULL dereference. If an untrusted XML document was parsed in recovery mode and post-validated, the flaw could be used to crash the application. The highest threat from this vulnerability is to system availability.\n\n * CVE-2021-3541: A flaw was found in libxml2. Exponential entity expansion attack its possible bypassing all existing protection mechanisms and leading to denial of service.",
