Package : musl
Version : 1.1.16-3+deb9u1
CVE ID : CVE-2020-28928
Debian Bug : 975365
The wcsnrtombs function in all musl libc versions up through 1.2.1
has been found to have multiple bugs in handling of destination
buffer size when limiting the input character count, which can
lead to infinite loop with no forward progress (no overflow) or
writing past the end of the destination buffers.
For Debian 9 stretch, this problem has been fixed in version
1.1.16-3+deb9u1.
We recommend that you upgrade your musl packages.
For the detailed security status of musl please refer to
