kernel: kvm: invalid parameter passing in kvm_iommu_map_pages()

The kvm_iommu_map_pages function in virt/kvm/iommu.c in the Linux kernel through 3.16.1 miscalculates the number of pages during the handling of a mapping failure, which allows guest OS users to (1) cause a denial of service (host OS memory corruption) or possibly have unspecified other impact by triggering a large gfn value or (2) cause a denial of service (host OS memory consumption) by triggering a small gfn value that leads to permanently pinned pages.

php: integer overflow in unserialize()

Integer overflow in the object_custom function in ext/standard/var_unserializer.c in PHP before 5.4.34, 5.5.x before 5.5.18, and 5.6.x before 5.6.2 allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via an argument to the unserialize function that triggers calculation of a large length value.

rsyslog: integer overflow in PRI parsing

Integer overflow in rsyslog before 7.6.7 and 8.x before 8.4.2 and sysklogd 1.5 and earlier allows remote attackers to cause a denial of service (crash) via a large priority (PRI) value. NOTE: this vulnerability exists because of an incomplete fix for CVE-2014-3634.

EMC Documentum Web Development Kit (WDK) before 6.8 does not properly generate random numbers for a certain parameter related to Webtop components, which makes it easier for remote attackers to conduct phishing attacks via brute-force attempts to predict the parameter value.

lz4: LZ4_decompress_generic() integer overflow (32-bit arches)

Yann Collet LZ4 before r119, when used on certain 32-bit platforms that allocate memory beyond 0x80000000, does not properly detect integer overflows, which allows context-dependent attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact via a crafted Literal Run, a different vulnerability than CVE-2014-4611.

Integer overflow in the tr_bitfieldEnsureNthBitAlloced function in bitfield.c in Transmission before 2.84 allows remote attackers to cause a denial of service and possibly execute arbitrary code via a crafted peer message, which triggers an out-of-bounds write.

Multiple integer overflows in the HelpServ module (mod-helpserv.c) in srvx 1.3.1 allow remote authenticated IRCops or HelpServ bot managers to cause a denial of service (infinite loop) via a large value in the EmptyInterval parameter or certain other interval configurations.

libvncserver: integer overflow flaw, leading to a heap-based buffer overflow in screen size handling

Integer overflow in the MallocFrameBuffer function in vncviewer.c in LibVNCServer 0.9.9 and earlier allows remote VNC servers to cause a denial of service (crash) and possibly execute arbitrary code via an advertisement for a large screen size, which triggers a heap-based buffer overflow.

libvncserver: server divide-by-zero flaw in scaling factor handling

The rfbProcessClientNormalMessage function in libvncserver/rfbserver.c in LibVNCServer 0.9.9 and earlier allows remote attackers to cause a denial of service (divide-by-zero error and server crash) via a zero value in the scaling factor in a (1) PalmVNCSetScaleFactor or (2) SetScale message.

python: buffer() integer overflow leading to out of bounds read

Integer overflow in bufferobject.c in Python before 2.7.8 allows context-dependent attackers to obtain sensitive information from process memory via a large size and offset in a "buffer" function.

Trove: potential leak of passwords into log files

The processutils.execute function in OpenStack oslo-incubator, Cinder, Nova, and Trove before 2013.2.4 and 2014.1 before 2014.1.3 allows local users to obtain passwords from commands that cause a ProcessExecutionError by reading the log.

Trove: potential leak of passwords into log files

The strutils.mask_password function in the OpenStack Oslo utility library, Cinder, Nova, and Trove before 2013.2.4 and 2014.1 before 2014.1.3 does not properly mask passwords when logging commands, which allows local users to obtain passwords by reading the log.

Integer overflow in SampleTable.cpp in libstagefright in Android before 5.0.0 has unspecified impact and attack vectors, aka internal bug 15342615.

rpm: integer overflow and stack overflow in CPIO header parsing

Integer overflow in RPM 4.12 and earlier allows remote attackers to execute arbitrary code via a crafted CPIO header in the payload section of an RPM file, which triggers a stack-based buffer overflow.

icu: integer truncation in the resolveImplicitLevels function

The resolveImplicitLevels function in common/ubidi.c in the Unicode Bidirectional Algorithm implementation in ICU4C in International Components for Unicode (ICU) before 55.1 uses an integer data type that is inconsistent with a header file, which allows remote attackers to cause a denial of service (incorrect malloc followed by invalid free) or possibly execute arbitrary code via crafted text.

jasper: dec->numtiles off-by-one check in jpc_dec_process_sot() (oCERT-2015-001)

Off-by-one error in the jpc_dec_process_sot function in JasPer 1.900.1 and earlier allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via a crafted JPEG 2000 image, which triggers a heap-based buffer overflow.

Integer overflow in Adobe Reader and Acrobat 10.x before 10.1.13 and 11.x before 11.0.10 on Windows and OS X allows attackers to execute arbitrary code via unspecified vectors.

tcpdump: denial of service in verbose mode using malformed OLSR payload

Integer underflow in the olsr_print function in tcpdump 3.9.6 through 4.6.2, when in verbose mode, allows remote attackers to cause a denial of service (crash) via a crafted length value in an OLSR frame.

The check_diskio plugin 3.2.6 and earlier for Nagios and Icinga allows local users to write to arbitrary files via a symlink attack on a temporary file with a predictable name (tmp/check_diskio_status-*-*).

jasper: incorrect component number check in COC, RGN and QCC marker segment decoders (oCERT-2014-009)

Multiple off-by-one errors in the (1) jpc_dec_cp_setfromcox and (2) jpc_dec_cp_setfromrgn functions in jpc/jpc_dec.c in JasPer 1.900.1 and earlier allow remote attackers to execute arbitrary code via a crafted jp2 file, which triggers a heap-based buffer overflow.
