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.
