Vulnerabilidades

perl-MDK-Common 1.1.11 and 1.1.24, 1.2.9 through 1.2.14, and possibly other versions, in Mandriva Linux does not properly handle strings when writing them to configuration files, which allows attackers to gain privileges via "special characters" in unspecified vectors.

Buffer overflow in the polymorphic opcode support in the Regular Expression Engine (regcomp.c) in Perl 5.8 allows context-dependent attackers to execute arbitrary code by switching from byte to Unicode (UTF) characters in a regular expression.

Integer overflow in the bdfReadCharacters function in bdfread.c in (1) X.Org libXfont before 20070403 and (2) freetype 2.3.2 and earlier allows remote authenticated users to execute arbitrary code via crafted BDF fonts, which result in a heap overflow.

Integer overflow in the FontFileInitTable function in X.Org libXfont before 20070403 allows remote authenticated users to execute arbitrary code via a long first line in the fonts.dir file, which results in a heap overflow.

Race condition in the (1) load_elf_library and (2) binfmt_aout function calls for uselib in Linux kernel 2.4 through 2.429-rc2 and 2.6 through 2.6.10 allows local users to execute arbitrary code by manipulating the VMA descriptor.

The 64 bit ELF support in Linux kernel 2.6 before 2.6.10, on 64-bit architectures, does not properly check for overlapping VMA (virtual memory address) allocations, which allows local users to cause a denial of service (system crash) or execute arbitrary code via a crafted ELF or a.out file.

sudo before 1.6.8p2 allows local users to execute arbitrary commands by using "()" style environment variables to create functions that have the same name as any program within the bash script that is called without using the program's full pathname.

The der_chop script in the openssl package in Trustix Secure Linux 1.5 through 2.1 and other operating systems allows local users to overwrite files via a symlink attack on temporary files.

Off-by-one error in passwd 0.68 and earlier, when using the --stdin option, causes passwd to use the first 78 characters of a password instead of the first 79, which results in a small reduction of the search space required for brute force attacks.

Memory leak in passwd 0.68 allows local users to cause a denial of service (memory consumption) via a large number of failed read attempts from the password buffer.

Format string vulnerability in Speedtouch USB driver before 1.3.1 allows local users to execute arbitrary code via (1) modem_run, (2) pppoa2, or (3) pppoa3.

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.

Multiple unknown vulnerabilities in Linux kernel 2.6 allow local users to gain privileges or access kernel memory, a different set of vulnerabilities than those identified in CVE-2004-0495, as found by the Sparse source code checking tool.

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.

The e1000 driver for Linux kernel 2.4.26 and earlier does not properly initialize memory before using it, which allows local users to read portions of kernel memory. NOTE: this issue was originally incorrectly reported as a "buffer overflow" by some sources.

A race condition in the way env_start and env_end pointers are initialized in the execve system call and used in fs/proc/base.c on Linux 2.4 allows local users to cause a denial of service (crash).

Kerberos FTP client allows remote FTP sites to execute arbitrary code via a pipe (|) character in a filename that is retrieved by the client.
