- 9.8CVE-2021-24036EPSS 3.3%
Passing an attacker controlled size when creating an IOBuf could cause integer overflow, leading to an out of bounds write on the heap with the possibility of remote code execution. This issue affects versions of folly prior to v2021.07.22…
- 9.8CVE-2020-1900EPSS 1.4%
When unserializing an object with dynamic properties HHVM needs to pre-reserve the full size of the dynamic property array before inserting anything into it. Otherwise the array might resize, invalidating previously stored references. This…
- 7.5CVE-2020-1899EPSS 1.2%
The unserialize() function supported a type code, "S", which was meant to be supported only for APC serialization. This type code allowed arbitrary memory addresses to be accessed as if they were static StringData objects. This issue affec…
- 7.5CVE-2020-1898EPSS 1.2%
