  This update fixes a security issue:
  The iconv() function in the GNU C Library versions 2.39 and older may
  overflow the output buffer passed to it by up to 4 bytes when converting
  strings to the ISO-2022-CN-EXT character set, which may be used to crash
  an application or overwrite a neighbouring variable.
  For more information, see:
    https://www.cve.org/CVERecord?id=CVE-2024-2961

+Subject: [PATCH] Fix use of __pthread_attr_copy in mq_notify (bug 27896)
+
+__pthread_attr_copy can fail and does not initialize the attribute
+structure in that case.
+
+If __pthread_attr_copy is never called and there is no allocated
+attribute, pthread_attr_destroy should not be called, otherwise
+there is a null pointer dereference in rt/tst-mqueue6.
+
+Fixes commit 42d359350510506b87101cf77202fefcbfc790cb
+("Use __pthread_attr_copy in mq_notify (bug 27896)").
