security flaw

Multiple buffer overflows in PHP before 5.2.1 allow attackers to cause a denial of service and possibly execute arbitrary code via unspecified vectors in the (1) session, (2) zip, (3) imap, and (4) sqlite extensions; (5) stream filters; and the (6) str_replace, (7) mail, (8) ibase_delete_user, (9) ibase_add_user, and (10) ibase_modify_user functions. NOTE: vector 6 might actually be an integer overflow (CVE-2007-1885). NOTE: as of 20070411, vector (3) might involve the imap_mail_compose function (CVE-2007-1825).

security flaw

Buffer underflow in PHP before 5.2.1 allows attackers to cause a denial of service via unspecified vectors involving the sapi_header_op function.

security flaw

Multiple format string vulnerabilities in PHP before 5.2.1 might allow attackers to execute arbitrary code via format string specifiers to (1) all of the *print functions on 64-bit systems, and (2) the odbc_result_all function.

PHP before 5.2.1 allows attackers to bypass safe_mode and open_basedir restrictions via unspecified vectors in the session extension. NOTE: it is possible that this issue is a duplicate of CVE-2006-6383.

security flaw

Unspecified vulnerability in PHP before 5.2.1 allows attackers to "clobber" certain super-global variables via unspecified vectors.

security flaw

sdiff 2.7 in the diffutils package allows local users to overwrite files via a symlink attack.

dump in Red Hat Linux 6.2 trusts the pathname specified by the RSH environmental variable, which allows local users to obtain root privileges by modifying the RSH variable to point to a Trojan horse program.

security flaw

Some functions that implement the locale subsystem on Unix do not properly cleanse user-injected format strings, which allows local attackers to execute arbitrary commands via functions such as gettext and catopen.

security flaw

Off-by-one error in the channel code of OpenSSH 2.0 through 3.0.2 allows local users or remote malicious servers to gain privileges.

security flaw

Squid before 2.3STABLE5 in HTTP accelerator mode does not enable access control lists (ACLs) when the httpd_accel_host and http_accel_with_proxy off settings are used, which allows attackers to bypass the ACLs and conduct unauthorized activities such as port scanning.

security flaw

The Linux kernel 2.4.20 and earlier, and 2.5.x, when running on x86 systems, allows local users to cause a denial of service (hang) via the emulation mode, which does not properly clear TF and NT EFLAGs.

security flaw

The do_mremap function for the mremap system call in Linux 2.2 to 2.2.25, 2.4 to 2.4.24, and 2.6 to 2.6.2, does not properly check the return value from the do_munmap function when the maximum number of VMA descriptors is exceeded, which allows local users to gain root privileges, a different vulnerability than CAN-2003-0985.

security flaw

Linux kernel does not properly convert 64-bit file offset pointers to 32 bits, which allows local users to access portions of kernel memory.

ProFTPD 1.2.9 treats the Allow and Deny directives for CIDR based ACL entries as if they were AllowAll, which could allow FTP clients to bypass intended access restrictions.

security flaw

Format string vulnerability in use_syslog() function in LPRng 3.6.24 allows remote attackers to execute arbitrary commands.

security flaw

The memory_limit functionality in PHP 4.x up to 4.3.7, and 5.x up to 5.0.0RC3, under certain conditions such as when register_globals is enabled, allows remote attackers to execute arbitrary code by triggering a memory_limit abort during execution of the zend_hash_init function and overwriting a HashTable destructor pointer before the initialization of key data structures is complete.

security flaw

Floating point information leak in the context switch code for Linux 2.4.x only checks the MFH bit but does not verify the FPH owner, which allows local users to read register values of other processes by setting the MFH bit.

security flaw

When using the LD_PRELOAD environmental variable in SUID or SGID applications, glibc does not verify that preloaded libraries in /etc/ld.so.cache are also SUID/SGID, which could allow a local user to overwrite arbitrary files by loading a library from /lib or /usr/lib.

security flaw

The strip_tags function in PHP 4.x up to 4.3.7, and 5.x up to 5.0.0RC3, does not filter null (\0) characters within tag names when restricting input to allowed tags, which allows dangerous tags to be processed by web browsers such as Internet Explorer and Safari, which ignore null characters and facilitate the exploitation of cross-site scripting (XSS) vulnerabilities.

security flaw

Unknown vulnerability in Linux kernel 2.x may allow local users to modify the group ID of files, such as NFS exported files in kernel 2.4.
