fontconfig: Possible double free due to insufficiently validated cache files

fontconfig before 2.12.1 does not validate offsets, which allows local users to trigger arbitrary free calls and consequently conduct double free attacks and execute arbitrary code via a crafted cache file.

HTTPD: sets environmental variable based on user supplied Proxy request header

The Apache HTTP Server through 2.4.23 follows RFC 3875 section 4.1.18 and therefore does not protect applications from the presence of untrusted client data in the HTTP_PROXY environment variable, which might allow remote attackers to redirect an application's outbound HTTP traffic to an arbitrary proxy server via a crafted Proxy header in an HTTP request, aka an "httpoxy" issue. NOTE: the vendor states "This mitigation has been assigned the identifier CVE-2016-5387"; in other words, this is not a CVE ID for a vulnerability.

Mozilla: Malicious WebGL content crash when writing strings (MFSA 2015-14)

The WebGL implementation in Mozilla Firefox before 36.0 does not properly allocate memory for copying an unspecified string to a shader's compilation log, which allows remote attackers to cause a denial of service (application crash) via crafted WebGL content.

Mozilla: Buffer overflow in libstagefright during MP4 video playback (MFSA 2015-17)

Buffer overflow in libstagefright in Mozilla Firefox before 36.0 allows remote attackers to execute arbitrary code via a crafted MP4 video that is improperly handled during playback.

mysql: unspecified vulnerability in subcomponent: Server: Privileges (CPU July 2016)

Unspecified vulnerability in Oracle MySQL 5.6.30 and earlier and 5.7.12 and earlier allows remote administrators to affect availability via vectors related to Server: Privileges.

mysql: unspecified vulnerability in subcomponent: Server: RBR (CPU July 2016)

Unspecified vulnerability in Oracle MySQL 5.5.49 and earlier, 5.6.30 and earlier, and 5.7.12 and earlier and MariaDB before 5.5.50, 10.0.x before 10.0.26, and 10.1.x before 10.1.15 allows remote administrators to affect availability via vectors related to Server: RBR.

Mozilla: Buffer overflow during CSS restyling (MFSA 2015-20)

The nsTransformedTextRun::SetCapitalization function in Mozilla Firefox before 36.0 allows remote attackers to execute arbitrary code or cause a denial of service (out-of-bounds read of heap memory) via a crafted Cascading Style Sheets (CSS) token sequence that triggers a restyle or reflow operation.

Kernel: powerpc: tm: crash via exec system call on PPC

The start_thread function in arch/powerpc/kernel/process.c in the Linux kernel through 4.6.3 on powerpc platforms mishandles transactional state, which allows local users to cause a denial of service (invalid process state or TM Bad Thing exception, and system crash) or possibly have unspecified other impact by starting and suspending a transaction before an exec system call.

kernel: Heap buffer overflow in hiddev driver

Multiple heap-based buffer overflows in the hiddev_ioctl_usage function in drivers/hid/usbhid/hiddev.c in the Linux kernel through 4.6.3 allow local users to cause a denial of service or possibly have unspecified other impact via a crafted (1) HIDIOCGUSAGES or (2) HIDIOCSUSAGES ioctl call.

gd: Invalid color index not properly handled

The gdImageCropThreshold function in gd_crop.c in the GD Graphics Library (aka libgd) before 2.2.3, as used in PHP before 7.0.9, allows remote attackers to cause a denial of service (application crash) via an invalid color index.

Mozilla: Buffer underflow during MP3 playback (MFSA 2015-21)

Stack-based buffer underflow in the mozilla::MP3FrameParser::ParseBuffer function in Mozilla Firefox before 36.0 allows remote attackers to obtain sensitive information from process memory via a malformed MP3 file that improperly interacts with memory allocation during playback.

Mozilla: Crash using DrawTarget in Cairo graphics library (MFSA 2015-22)

The mozilla::layers::BufferTextureClient::AllocateForSurface function in Mozilla Firefox before 36.0 allows remote attackers to cause a denial of service (out-of-bounds write of zero values, and application crash) via vectors that trigger use of DrawTarget and the Cairo library for image drawing.

Directory traversal vulnerability in KArchive before 5.24, as used in KDE Frameworks, allows remote attackers to write to arbitrary files via a ../ (dot dot slash) in a filename in an archive file, related to KNewsstuff downloads.

libidn: Out of bounds stack read in idna_to_ascii_4i

The idna_to_ascii_4i function in lib/idna.c in libidn before 1.33 allows context-dependent attackers to cause a denial of service (out-of-bounds read and crash) via 64 bytes of input.

Mozilla: Use-after-free in Developer Console date with OpenType Sanitiser (MFSA 2015-23)

Multiple use-after-free vulnerabilities in OpenType Sanitiser, as used in Mozilla Firefox before 36.0, might allow remote attackers to trigger problematic Developer Console information or possibly have unspecified other impact by leveraging incorrect macro expansion, related to the ots::ots_gasp_parse function.

Mozilla: Local files or privileged URLs in pages can be opened into new tabs (MFSA 2015-25)

Mozilla Firefox before 36.0 allows user-assisted remote attackers to read arbitrary files or execute arbitrary JavaScript code with chrome privileges via a crafted web site that is accessed with unspecified mouse and keyboard actions.

libgcrypt: PRNG output is predictable

The mixing functions in the random number generator in Libgcrypt before 1.5.6, 1.6.x before 1.6.6, and 1.7.x before 1.7.3 and GnuPG before 1.4.21 make it easier for attackers to obtain the values of 160 bits by leveraging knowledge of the previous 4640 bits.

Kernel: mm: try_to_unmap_cluster() should lock_page() before mlocking

The try_to_unmap_cluster function in mm/rmap.c in the Linux kernel before 3.14.3 does not properly consider which pages must be locked, which allows local users to cause a denial of service (system crash) by triggering a memory-usage pattern that requires removal of page-table mappings.

Mozilla Firefox before 36.0 does not properly restrict transitions of JavaScript objects from a non-extensible state to an extensible state, which allows remote attackers to bypass a Caja Compiler sandbox protection mechanism or a Secure EcmaScript sandbox protection mechanism via a crafted web site.

Mozilla: UI Tour whitelisted sites in background tab can spoof foreground tabs (MFA 2015-26)

The UITour::onPageEvent function in Mozilla Firefox before 36.0 does not ensure that an API call originates from a foreground tab, which allows remote attackers to conduct spoofing and clickjacking attacks by leveraging access to a UI Tour web site.
