Bug 611344 – <sys-libs/glibc-2.31-r7: iconv program can hang when invoked with the -c option

• Status: RESOLVED FIXED
• Product: Gentoo Security

[Description Thomas Deutschmann (RETIRED) 2017-03-01 23:38:04 UTC]

The iconv program (not the iconv function) provided by glibc can hang (enter an infinite loop) when invoked with the -c option and an invalid multi-byte sequence is encountered in the input. See $URL for more details.

Now that 2.32-r3 is stabilized, is it possible to cleanup the vulnerable versions here?
