PatchTheCVECVE-2021-44499: An issue was discovered in FIS GT.M through V7.0-000 (related to the YottaDB code base)
CVE-2021-44499 is a high-severity flaw (CVSS 7.5) affecting gt.m. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
An issue was discovered in FIS GT.M through V7.0-000 (related to the YottaDB code base). Using crafted input, an attacker can cause a call to $Extract to force an signed integer holding the size of a buffer to take on a large negative number, which is then used as the length of a memcpy call that occurs on the stack, causing a buffer overflow.
Why this priority
- High severity
- Remotely exploitable, no login, no user action
A fixed release or distro patch exists.
