Mandriva Linux Security Advisory 2013-283

Posted Nov 25, 2013

Authored by Mandriva | Site mandriva.com

Mandriva Linux Security Advisory 2013-283 - Updated glibc packages fix multiple security issues. Integer overflow in string/strcoll_l.c in the GNU C Library (aka glibc or libc6) 2.17 and earlier allows context-dependent attackers to cause a denial of service or possibly execute arbitrary code via a long string, which triggers a heap-based buffer overflow. Stack-based buffer overflow in string/strcoll_l.c in the GNU C Library 2.17 and earlier allows context-dependent attackers to cause a denial of service or possibly execute arbitrary code via a long string that triggers a malloc failure and use of the alloca function. pt_chown in GNU C Library before 2.18 does not properly check permissions for tty files, which allows local users to change the permission on the files and obtain access to arbitrary pseudo-terminals by leveraging a FUSE file system. Various other issues were also addressed.
