perl regular expression UTF parsing errors

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.

xscreensaver authentication bypass

XScreenSaver 4.10, when using a remote directory service for credentials, does not properly handle the results from the getpwuid function in drivers/lock.c when there is no network connectivity, which causes XScreenSaver to crash and unlock the screen and allows local users to bypass authentication.

vorbis: zero-dim codebooks can cause crash, infinite loop or heap overflow

Xiph.org libvorbis 1.2.0 and earlier does not properly handle a zero value for codebook.dim, which allows remote attackers to cause a denial of service (crash or infinite loop) or trigger an integer overflow.

vorbis: integer overflow in partvals computation

Integer overflow in residue partition value (aka partvals) evaluation in Xiph.org libvorbis 1.2.0 and earlier allows remote attackers to execute arbitrary code via a crafted OGG file, which triggers a heap overflow.

security flaw

A "stack overwrite" vulnerability in GnuPG (gpg) 1.x before 1.4.6, 2.x before 2.0.2, and 1.9.0 through 1.9.95 allows attackers to execute arbitrary code via crafted OpenPGP packets that cause GnuPG to dereference a function pointer from deallocated stack memory.

Multiple font integer overflows (CVE-2007-1352)

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.

Multiple font integer overflows (CVE-2007-1352)

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.

dhcpd stack-based buffer overlow

Stack-based buffer overflow in the cons_options function in options.c in dhcpd in OpenBSD 4.0 through 4.2, and some other dhcpd implementations based on ISC dhcp-2, allows remote attackers to execute arbitrary code or cause a denial of service (daemon crash) via a DHCP request specifying a maximum message size smaller than the minimum IP MTU.

vorbis: integer oveflow caused by huge codebooks

Integer overflow in a certain quantvals and quantlist calculation in Xiph.org libvorbis 1.2.0 and earlier allows remote attackers to cause a denial of service (crash) or execute arbitrary code via a crafted OGG file with a large virtual space for its codebook, which triggers a heap overflow.

libxslt: fixed-sized steps array overflow via "template match" condition in XSL file

Buffer overflow in pattern.c in libxslt before 1.1.24 allows context-dependent attackers to cause a denial of service (crash) and possibly execute arbitrary code via an XSL style sheet file with a long XSLT "transformation match" condition that triggers a large number of steps.

security flaw

The getifaddrs function in GNU libc (glibc) 2.2.4 and earlier allows local users to cause a denial of service by sending spoofed messages as other users to the kernel netlink interface.

security flaw

The SMB SID snooping capability in Ethereal 0.9.15 to 0.10.4 allows remote attackers to cause a denial of service (process crash) via a handle without a policy name, which causes a null dereference.

security flaw

The SNMP dissector in Ethereal 0.8.15 through 0.10.4 allows remote attackers to cause a denial of service (process crash) via a (1) malformed or (2) missing community string, which causes an out-of-bounds read.

Buffer overflow in the BMP loader in imlib2 before 1.1.2 allows remote attackers to execute arbitrary code via a specially-crafted BMP image, a different vulnerability than CVE-2004-0817.

security flaw

The iSNS dissector for Ethereal 0.10.3 through 0.10.4 allows remote attackers to cause a denial of service (process abort) via an integer overflow.

security flaw

The C-Media PCI sound driver in Linux before 2.4.21 does not use the get_user function to access userspace, which crosses security boundaries and may facilitate the exploitation of vulnerabilities, a different vulnerability than CVE-2003-0700.

security flaw

Various PDF viewers including (1) Adobe Acrobat 5.06 and (2) Xpdf 1.01 allow remote attackers to execute arbitrary commands via shell metacharacters in an embedded hyperlink.

security flaw

Multiple extfs backend scripts for GNOME virtual file system (VFS) before 1.0.1 may allow remote attackers to perform certain unauthorized actions via a gnome-vfs URI.

security flaw

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.

security flaw

gdk-pixbuf before 0.20 allows attackers to cause a denial of service (crash) via a malformed bitmap (BMP) file.
