 Mandriva Linux Security Advisory                         MDVSA-2010:112
 http://www.mandriva.com/security/
 _______________________________________________________________________

 Package : glibc
 Date    : June 8, 2010
 Affected: 2010.0
 _______________________________________________________________________

 Problem Description:

 Multiple vulnerabilities was discovered and fixed in glibc:
 
 Multiple integer overflows in the strfmon implementation in
 the GNU C Library (aka glibc or libc6) 2.10.1 and earlier allow
 context-dependent attackers to cause a denial of service (memory
 consumption or application crash) via a crafted format string, as
 demonstrated by a crafted first argument to the money_format function
 in PHP, a related issue to CVE-2008-1391 (CVE-2009-4880).
 
 nis/nss_nis/nis-pwd.c in the GNU C Library (aka glibc or libc6)
 2.7 and Embedded GLIBC (EGLIBC) 2.10.2 adds information from the
 passwd.adjunct.byname map to entries in the passwd map, which allows
 remote attackers to obtain the encrypted passwords of NIS accounts
 by calling the getpwnam function (CVE-2010-0015).
 
 The encode_name macro in misc/mntent_r.c in the GNU C Library (aka
 glibc or libc6) 2.11.1 and earlier, as used by ncpmount and mount.cifs,
 does not properly handle newline characters in mountpoint names, which
 allows local users to cause a denial of service (mtab corruption),
 or possibly modify mount options and gain privileges, via a crafted
 mount request (CVE-2010-0296).
 
 Integer signedness error in the elf_get_dynamic_info function
 in elf/dynamic-link.h in ld.so in the GNU C Library (aka glibc or
 libc6) 2.0.1 through 2.11.1, when the --verify option is used, allows
 user-assisted remote attackers to execute arbitrary code via a crafted
 ELF program with a negative value for a certain d_tag structure member
 in the ELF header (CVE-2010-0830).
 
 The updated packages have been patched to correct these issues.
