The ares_init:randomize_key function in c-ares, on platforms other than Windows, uses a weak facility for producing a random number sequence (Unix rand), which makes it easier for remote attackers to spoof DNS responses by guessing certain values.

HighCVSS 7.5 EPSS 1.4%
c-ares before 1.4.0 uses a predictable seed for the random number generator for the DNS Transaction ID field, which might allow remote attackers to spoof DNS responses by guessing the field value.
-
HighCVSS 7.5 EPSS 5.3%
Heap-based buffer overflow in cURL and libcURL 7.15.0 through 7.15.2 allows remote attackers to execute arbitrary commands via a TFTP URL (tftp://) with a valid hostname and a long path.

MediumCVSS 4.6 EPSS 0.52%
Multiple off-by-one errors in the cURL library (libcurl) 7.11.2 through 7.15.0 allow local users to trigger a buffer overflow and cause a denial of service or bypass PHP security restrictions via certain URLs that (1) are malformed in a way that prevents a terminating null byte f...

HighCVSS 10.0 EPSS 5.4%
Dispair 0.1 and 0.2 allows remote attackers to execute arbitrary shell commands via certain form fields.

HighCVSS 10.0 EPSS 18.1%
Buffer overflow in curl earlier than 6.0-1.1, and curl-ssl earlier than 6.0-1.2, allows remote attackers to execute arbitrary commands by forcing a long error message to be generated.
