GHSA-rrf5-grxg-q8mm
fzf contains an integer overflow vulnerability in the FuzzyMatchV2 function. When processing an input line of approximately 2,200,000 bytes with a pattern length of 999 bytes, an integer overflow occurs, causing the Go runtime to detect invalid slice bounds and terminate the process with a non-recoverable panic. This issue was fixed in version 0.73.1.
AI Analysis
Technical Summary
The fzf tool is vulnerable to an integer overflow in its FuzzyMatchV2 function. Specifically, when the input line length is around 2,200,000 bytes and the pattern length is 999 bytes, the multiplication of these values overflows the integer type used. This leads to invalid slice bounds in Go, triggering a runtime panic that crashes the process. The vulnerability results in a denial of service via application crash. The issue has been addressed and fixed in fzf version 0.73.1.
Potential Impact
The vulnerability causes a denial of service by crashing the fzf process when processing specially crafted large inputs. There is no indication of code execution or data corruption beyond the crash. No known exploits are reported in the wild.
Mitigation Recommendations
Upgrade fzf to version 0.73.1 or later where this integer overflow vulnerability has been fixed. No other mitigations are indicated.
