Off-by-one error in the DTLS implementation in OpenSSL 0.9.8 before 0.9.8f allows remote attackers to execute arbitrary code via unspecified vectors.

Certificate Server 7.2 in Red Hat Certificate System (RHCS) does not properly handle new revocations that occur while a Certificate Revocation List (CRL) is being generated, which might prevent certain revoked certificates from appearing on the CRL quickly and allow users with revoked certificates to bypass the intended CRL.

pygrub (tools/pygrub/src/GrubConf.py) in Xen 3.0.3, when booting a guest domain, allows local users with elevated privileges in the guest domain to execute arbitrary commands in domain 0 via a crafted grub.conf file whose contents are used in exec statements.

The swap_char2b function in X.Org X Font Server (xfs) before 1.0.5 allows context-dependent attackers to execute arbitrary code via (1) QueryXBitmaps and (2) QueryXExtents protocol requests with crafted size values that specify an arbitrary number of bytes to be swapped on the heap, which triggers heap corruption.

Sign extension error in the ReadDIBImage function in ImageMagick before 6.3.5-9 allows context-dependent attackers to execute arbitrary code via a crafted width value in an image file, which triggers an integer overflow and a heap-based buffer overflow.

Off-by-one error in the ReadBlobString function in blob.c in ImageMagick before 6.3.5-9 allows context-dependent attackers to execute arbitrary code via a crafted image file, which triggers the writing of a '\0' character to an out-of-bounds address.

Multiple integer overflows in ImageMagick before 6.3.5-9 allow context-dependent attackers to execute arbitrary code via a crafted (1) .dcm, (2) .dib, (3) .xbm, (4) .xcf, or (5) .xwd image file, which triggers a heap-based buffer overflow.

ImageMagick before 6.3.5-9 allows context-dependent attackers to cause a denial of service via a crafted image file that triggers (1) an infinite loop in the ReadDCMImage function, related to ReadBlobByte function calls; or (2) an infinite loop in the ReadXCFImage function, related to ReadBlobMSBLong function calls.

Heap-based buffer overflow in the flac_buffer_copy function in libsndfile 1.0.17 and earlier might allow remote attackers to execute arbitrary code via a FLAC file with crafted PCM data containing a block with a size that exceeds the previous block size.

Multiple integer overflows in the imageop module in Python 2.5.1 and earlier allow context-dependent attackers to cause a denial of service (application crash) and possibly obtain sensitive information (memory contents) via crafted arguments to (1) the tovideo method, and unspecified other vectors related to (2) imageop.c, (3) rbgimgmodule.c, and other files, which trigger heap-based buffer overflows.

The Open Phone Abstraction Library (opal), as used by (1) Ekiga before 2.0.10 and (2) OpenH323 before 2.2.4, allows remote attackers to cause a denial of service (crash) via an invalid Content-Length header field in Session Initiation Protocol (SIP) packets, which causes a \0 byte to be written to an "attacker-controlled address."

pwlib, as used by Ekiga 2.0.5 and possibly other products, allows remote attackers to cause a denial of service (application crash) via a long argument to the PString::vsprintf function, related to a "memory management flaw". NOTE: this issue was originally reported as being in the SIPURL::GetHostAddress function in Ekiga (formerly GnomeMeeting).

curl/interface.c in the cURL library (aka libcurl) in PHP 5.2.4 and 5.2.5 allows context-dependent attackers to bypass safe_mode and open_basedir restrictions and read arbitrary files via a file:// request containing a \x00 sequence, a different vulnerability than CVE-2006-2563.

Directory traversal vulnerability in the Archive::Tar Perl module 1.36 and earlier allows user-assisted remote attackers to overwrite arbitrary files via a TAR archive that contains a file whose name is an absolute path or has ".." sequences.

bgpd in Quagga before 0.99.9 allows explicitly configured BGP peers to cause a denial of service (crash) via a malformed (1) OPEN message or (2) a COMMUNITY attribute, which triggers a NULL pointer dereference. NOTE: vector 2 only exists when debugging is enabled.

The setlocale function in PHP before 5.2.4 allows context-dependent attackers to cause a denial of service (application crash) via a long string in the locale parameter. NOTE: this might not be a vulnerability in most web server environments that support multiple threads, unless this issue can be demonstrated for code execution.

PHP before 5.2.3 allows context-dependent attackers to cause a denial of service (application crash) via (1) a long string in the pattern parameter to the glob function; or (2) a long string in the string parameter to the fnmatch function, accompanied by a pattern parameter value with undefined characteristics, as demonstrated by a "*[1]e" value. NOTE: this might not be a vulnerability in most web server environments that support multiple threads, unless these issues can be demonstrated for code execution.

The Linux kernel before 2.4.36-rc1 has a race condition. It was possible to bypass systrace policies by flooding the ptraced process with SIGCONT signals, which can can wake up a PTRACED process.

The regular expression parser in TCL before 8.4.17, as used in PostgreSQL 8.2 before 8.2.6, 8.1 before 8.1.11, 8.0 before 8.0.15, and 7.4 before 7.4.19, allows context-dependent attackers to cause a denial of service (infinite loop) via a crafted regular expression.

Heap-based buffer overflow in the doInterval function in regexcmp.cpp in libicu in International Components for Unicode (ICU) 3.8.1 and earlier allows context-dependent attackers to cause a denial of service (memory consumption) and possibly have unspecified other impact via a regular expression that writes a large amount of data to the backtracking stack. NOTE: some of these details are obtained from third party information.
