Summary
libcroco vulnerabilities
Details
It was discovered that Libcroco was incorrectly accessing data structures when reading bytes from memory, which could cause a heap buffer overflow. An attacker could possibly use this issue to cause a denial of service. This issue only affected Ubuntu 14.04 LTS. (CVE-2017-7960)
It was discovered that Libcroco was incorrectly handling invalid UTF-8 values when processing CSS files. An attacker could possibly use this issue to cause a denial of service. (CVE-2017-8834, CVE-2017-8871)
It was discovered that Libcroco was incorrectly implementing recursion in one of its parsing functions, which could cause an infinite recursion loop and a stack overflow due to stack consumption. An attacker could possibly use this issue to cause a denial of service. (CVE-2020-12825)
