CVE-2021-24031 1 Facebook 1 Zstandard 2021-04-14 2.1 LOW 5.5 MEDIUM
In the Zstandard command-line utility prior to v1.4.1, output files were created with default permissions. Correct file permissions (matching the input) would only be set at completion time. Output files could therefore be readable or writable to unintended parties.
CVE-2020-1896 1 Facebook 1 Hermes 2021-03-26 6.8 MEDIUM 9.8 CRITICAL
A stack overflow vulnerability in Facebook Hermes 'builtin apply' prior to commit 86543ac47e59c522976b5632b8bf9a2a4583c7d2 (https://github.com/facebook/hermes/commit/86543ac47e59c522976b5632b8bf9a2a4583c7d2) allows attackers to potentially execute arbitrary code via crafted JavaScript. Note that this is only exploitable if the application using Hermes permits evaluation of untrusted JavaScript. Hence, most React Native applications are not affected.
CVE-2021-24029 1 Facebook 2 Mvfst, Proxygen 2021-03-23 5.0 MEDIUM 7.5 HIGH
A packet of death scenario is possible in mvfst via a specially crafted message during a QUIC session, which causes a crash via a failed assertion. Per QUIC specification, this particular message should be treated as a connection error. This issue affects mvfst versions prior to commit a67083ff4b8dcbb7ee2839da6338032030d712b0 and proxygen versions prior to v2021.03.15.00.
CVE-2020-1899 1 Facebook 1 Hhvm 2021-03-18 5.0 MEDIUM 7.5 HIGH
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 affected HHVM prior to v4.32.3, between versions 4.33.0 and 4.56.0, 4.57.0, 4.58.0, 4.58.1, 4.59.0, 4.60.0, 4.61.0, 4.62.0.
CVE-2020-1900 1 Facebook 1 Hhvm 2021-03-18 7.5 HIGH 9.8 CRITICAL
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 pre-reservation was not occurring in HHVM prior to v4.32.3, between versions 4.33.0 and 4.56.0, 4.57.0, 4.58.0, 4.58.1, 4.59.0, 4.60.0, 4.61.0, 4.62.0.
CVE-2020-1898 1 Facebook 1 Hhvm 2021-03-17 5.0 MEDIUM 7.5 HIGH
The fb_unserialize function did not impose a depth limit for nested deserialization. That meant a maliciously constructed string could cause deserialization to recurse, leading to stack exhaustion. This issue affected HHVM prior to v4.32.3, between versions 4.33.0 and 4.56.0, 4.57.0, 4.58.0, 4.58.1, 4.59.0, 4.60.0, 4.61.0, 4.62.0.
CVE-2020-1917 1 Facebook 1 Hhvm 2021-03-17 7.5 HIGH 9.8 CRITICAL
xbuf_format_converter, used as part of exif_read_data, was appending a terminating null character to the generated string, but was not using its standard append char function. As a result, if the buffer was full, it would result in an out-of-bounds write. This issue affects HHVM versions prior to 4.56.3, all versions between 4.57.0 and 4.80.1, all versions between 4.81.0 and 4.93.1, and versions 4.94.0, 4.95.0, 4.96.0, 4.97.0, 4.98.0.
CVE-2020-1916 1 Facebook 1 Hhvm 2021-03-17 7.5 HIGH 9.8 CRITICAL
An incorrect size calculation in ldap_escape may lead to an integer overflow when overly long input is passed in, resulting in an out-of-bounds write. This issue affects HHVM prior to 4.56.2, all versions between 4.57.0 and 4.78.0, 4.79.0, 4.80.0, 4.81.0, 4.82.0, 4.83.0.
CVE-2021-24033 1 Facebook 1 React-dev-utils 2021-03-16 6.8 MEDIUM 5.6 MEDIUM
react-dev-utils prior to v11.0.4 exposes a function, getProcessForPort, where an input argument is concatenated into a command string to be executed. This function is typically used from react-scripts (in Create React App projects), where the usage is safe. Only when this function is manually invoked with user-provided values (ie: by custom code) is there the potential for command injection. If you're consuming it from react-scripts then this issue does not affect you.
CVE-2021-24030 1 Facebook 1 Gameroom 2021-03-16 7.5 HIGH 9.8 CRITICAL
The fbgames protocol handler registered as part of Facebook Gameroom does not properly quote arguments passed to the executable. That allows a malicious URL to cause code execution. This issue affects versions prior to v1.26.0.
CVE-2021-24025 1 Facebook 1 Hhvm 2021-03-16 7.5 HIGH 9.8 CRITICAL
Due to incorrect string size calculations inside the preg_quote function, a large input string passed to the function can trigger an integer overflow leading to a heap overflow. This issue affects HHVM versions prior to 4.56.3, all versions between 4.57.0 and 4.80.1, all versions between 4.81.0 and 4.93.1, and versions 4.94.0, 4.95.0, 4.96.0, 4.97.0, 4.98.0.
CVE-2020-1918 1 Facebook 1 Hhvm 2021-03-15 5.0 MEDIUM 7.5 HIGH
In-memory file operations (ie: using fopen on a data URI) did not properly restrict negative seeking, allowing for the reading of memory prior to the in-memory buffer. This issue affects HHVM versions prior to 4.56.3, all versions between 4.57.0 and 4.80.1, all versions between 4.81.0 and 4.93.1, and versions 4.94.0, 4.95.0, 4.96.0, 4.97.0, 4.98.0.
CVE-2020-1919 1 Facebook 1 Hhvm 2021-03-15 5.0 MEDIUM 7.5 HIGH
Incorrect bounds calculations in substr_compare could lead to an out-of-bounds read when the second string argument passed in is longer than the first. This issue affects HHVM versions prior to 4.56.3, all versions between 4.57.0 and 4.80.1, all versions between 4.81.0 and 4.93.1, and versions 4.94.0, 4.95.0, 4.96.0, 4.97.0, 4.98.0.
CVE-2020-1921 1 Facebook 1 Hhvm 2021-03-15 5.0 MEDIUM 7.5 HIGH
In the crypt function, we attempt to null terminate a buffer using the size of the input salt without validating that the offset is within the buffer. This issue affects HHVM versions prior to 4.56.3, all versions between 4.57.0 and 4.80.1, all versions between 4.81.0 and 4.93.1, and versions 4.94.0, 4.95.0, 4.96.0, 4.97.0, 4.98.0.
CVE-2020-1915 1 Facebook 1 Hermes 2020-11-02 4.3 MEDIUM 7.5 HIGH
An out-of-bounds read in the JavaScript Interpreter in Facebook Hermes prior to commit 8cb935cd3b2321c46aa6b7ed8454d95c75a7fca0 allows attackers to cause a denial of service attack or possible further memory corruption via crafted JavaScript. Note that this is only exploitable if the application using Hermes permits evaluation of untrusted JavaScript. Hence, most React Native applications are not affected.
CVE-2019-11922 1 Facebook 1 Zstandard 2020-10-20 6.8 MEDIUM 8.1 HIGH
A race condition in the one-pass compression functions of Zstandard prior to version 1.3.8 could allow an attacker to write bytes out of bounds if an output buffer smaller than the recommended size was used.
CVE-2019-3563 1 Facebook 1 Wangle 2020-10-16 7.5 HIGH 9.8 CRITICAL
Wangle's LineBasedFrameDecoder contains logic for identifying newlines which incorrectly advances a buffer, leading to a potential underflow. This affects versions of Wangle prior to v2019.04.22.00
CVE-2019-3570 1 Facebook 1 Hiphop Virtual Machine 2020-10-16 7.5 HIGH 9.8 CRITICAL
Call to the scrypt_enc() function in HHVM can lead to heap corruption by using specifically crafted parameters (N, r and p). This happens if the parameters are configurable by an attacker for instance by providing the output of scrypt_enc() in a context where Hack/PHP code would attempt to verify it by re-running scrypt_enc() with the same parameters. This could result in information disclosure, memory being overwriten or crashes of the HHVM process. This issue affects versions 4.3.0, 4.4.0, 4.5.0, 4.6.0, 4.7.0, 4.8.0, versions 3.30.5 and below, and all versions in the 4.0, 4.1, and 4.2 series.
CVE-2018-6345 1 Facebook 1 Hhvm 2020-09-21 7.5 HIGH 9.8 CRITICAL
The function number_format is vulnerable to a heap overflow issue when its second argument ($dec_points) is excessively large. The internal implementation of the function will cause a string to be created with an invalid length, which can then interact poorly with other functions. This affects all supported versions of HHVM (3.30.1 and 3.27.5 and below).
CVE-2020-1913 1 Facebook 1 Hermes 2020-09-15 6.8 MEDIUM 8.1 HIGH
An Integer signedness error in the JavaScript Interpreter in Facebook Hermes prior to commit 2c7af7ec481ceffd0d14ce2d7c045e475fd71dc6 allows attackers to cause a denial of service attack or a potential RCE via crafted JavaScript. Note that this is only exploitable if the application using Hermes permits evaluation of untrusted JavaScript. Hence, most React Native applications are not affected.
