From 007c109b4594c5e63948bd08b4d5011ad76ffb10 Mon Sep 17 00:00:00 2001 From: Ben Wagner Date: Fri, 23 Oct 2020 08:29:14 +0200 Subject: [PATCH] * src/sfnt/pngshim.c (Load_SBit_Png): Fix memory leak (#59322). The issue is that `rows` is allocated but will not be freed in the event that the call to `png_read_image` fails and calls `longjmp`. --- ChangeLog | 7 +++++++ src/sfnt/pngshim.c | 1 + 2 files changed, 8 insertions(+) diff --git a/ChangeLog b/ChangeLog index 42f7c34ba..ff048b8ab 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,3 +1,10 @@ +2020-10-23 Ben Wagner + + * src/sfnt/pngshim.c (Load_SBit_Png): Fix memory leak (#59322). + + The issue is that `rows` is allocated but will not be freed in the + event that the call to `png_read_image` fails and calls `longjmp`. + 2020-10-20 Werner Lemberg * Version 2.10.4 released. diff --git a/src/sfnt/pngshim.c b/src/sfnt/pngshim.c index f55016122..d4e43a9f4 100644 --- a/src/sfnt/pngshim.c +++ b/src/sfnt/pngshim.c @@ -443,6 +443,7 @@ png_read_end( png, info ); DestroyExit: + FT_FREE( rows ); png_destroy_read_struct( &png, &info, NULL ); FT_Stream_Close( &stream ); -- 2.26.2
