Multiple heap-based buffer overflows in Mozilla Firefox before the Preview Release, Mozilla before 1.7.3, and Thunderbird before 0.8 allow remote attackers to cause a denial of service (application crash) or execute arbitrary code via (1) the "Send page" functionality, (2) certain responses from a malicious POP3 server, or (3) a link containing a non-ASCII hostname.
Stack-based buffer overflow in the writeGroup function in nsVCardObj.cpp for Mozilla Firefox before the Preview Release, Mozilla before 1.7.3, and Thunderbird before 0.8 allows remote attackers to execute arbitrary code via malformed VCard attachments that are not properly handled when previewing a message.
Heap-based buffer overflow in the OJPEGVSetField function in tif_ojpeg.c for libtiff 3.6.1 and earlier, when compiled with the OJPEG_SUPPORT (old JPEG support) option, allows remote attackers to execute arbitrary code via a malformed TIFF image.
Multiple vulnerabilities in the samba filesystem (smbfs) in Linux kernel 2.4 and 2.6 allow remote samba servers to cause a denial of service (crash) or gain sensitive information from kernel memory via a samba server (1) returning more data than requested to the smb_proc_read function, (2) returning a data offset from outside the samba packet to the smb_proc_readX function, (3) sending a certain TRANS2 fragmented packet to the smb_receive_trans2 function, (4) sending a samba packet with a certain header size to the smb_proc_readX_data function, or (5) sending a certain packet based offset for the data in a packet to the smb_receive_trans2 function.
Multiple vulnerabilities in libXpm for 6.8.1 and earlier, as used in XFree86 and other packages, include (1) multiple integer overflows, (2) out-of-bounds memory accesses, (3) directory traversal, (4) shell metacharacter, (5) endless loops, and (6) memory leaks, which could allow remote attackers to obtain sensitive information, cause a denial of service (application crash), or execute arbitrary code via a certain XPM image file. NOTE: it is highly likely that this candidate will be SPLIT into other candidates in the future, per CVE's content decisions.
The smb_recv_trans2 function call in the samba filesystem (smbfs) in Linux kernel 2.4 and 2.6 does not properly handle the re-assembly of fragmented packets correctly, which could allow remote samba servers to (1) read arbitrary kernel information or (2) raise a counter value to an arbitrary number by sending the first part of the fragmented packet multiple times.
The load_elf_binary function in the binfmt_elf loader (binfmt_elf.c) in Linux kernel 2.4.x up to 2.4.27, and 2.6.x up to 2.6.8, does not properly check return values from calls to the kernel_read function, which may allow local users to modify sensitive memory in a setuid program and execute arbitrary code.
The binfmt_elf loader (binfmt_elf.c) in Linux kernel 2.4.x up to 2.4.27, and 2.6.x up to 2.6.8, does not properly handle a failed call to the mmap function, which causes an incorrect mapped image and may allow local users to execute arbitrary code.
The binfmt_elf loader (binfmt_elf.c) in Linux kernel 2.4.x up to 2.4.27, and 2.6.x up to 2.6.8, may create an interpreter name string that is not NULL terminated, which could cause strings longer than PATH_MAX to be used, leading to buffer overflows that allow local users to cause a denial of service (hang) and possibly execute arbitrary code.
The open_exec function in the execve functionality (exec.c) in Linux kernel 2.4.x up to 2.4.27, and 2.6.x up to 2.6.8, allows local users to read non-readable ELF binaries by using the interpreter (PT_INTERP) functionality.
