radareorg/radare2: Out-of-bounds Read
CVE-2022-1452 is a high-severity out-of-bounds read vulnerability in radareorg/radare2 from Radareorg, with a CVSS 3.1 base score of 7.1 out of 10. It can be exploited with local access to the system by an unauthenticated attacker, but only if a user takes part, for example by opening a link or file. The record lists version 5.7.0 as the first without the flaw, so updating radareorg/radare2 to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.81% chance of exploitation within 30 days, higher than 57% of scored CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update radareorg/radare2 to 5.7.0 or a later version.
- Update Radare2 to 5.7.0 or a later version.
- Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.
