File opensc-CVE-2019-6502.patch of Package opensc.35664
From 0d7967549751b7032f22b437106b41444aff0ba9 Mon Sep 17 00:00:00 2001 From: Scott Gayou <sgayou@redhat.com> Date: Fri, 1 Mar 2019 13:11:06 -0600 Subject: [PATCH] Small memory leak fix (CVE-2019-6502 in #1586) CVE-2019-6502 was assigned to what appears to be a very minor memory leak that only occurs on an error-case in a CLI tool. If util_connect_card fails, we still need to release the sc context previously allocated by sc_context_create else memory will leak. --- src/tools/eidenv.c | 1 + 1 file changed, 1 insertion(+) diff --git a/src/tools/eidenv.c b/src/tools/eidenv.c index d8a7be62e4..d96ad4e742 100644 --- a/src/tools/eidenv.c +++ b/src/tools/eidenv.c @@ -403,6 +403,7 @@ int main(int argc, char **argv) r = util_connect_card(ctx, &card, opt_reader, opt_wait, 0); if (r) { fprintf(stderr, "Failed to connect to card: %s\n", sc_strerror(r)); + sc_release_context(ctx); return 1; }
