CVE-2021-3326
The iconv function in the GNU C Library (aka glibc or libc6) 2.32 and earlier, when processing invalid input sequences in the ISO-2022-JP-3 encoding, fails an assertion in the code path and aborts the program, potentially resulting in a denial of service.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.09%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
