A double free flaw was found in the way JasPer's jasperimagestopload() function parsed certain JPEG 2000 image files. A specially crafted file could cause an application using JasPer to crash.
Original report:

A use-after-free which leads to double-free vulnerability was found in Jasper JPEG-2000 library, in src/libjasper/mif/mifcod.c file.
553 case MIFHSAMP: 554 cmpt->sampperx = atoi(jastvparsergetval(tvp)); 555 break; 556 case MIFVSAMP: 557 cmpt->samppery = atoi(jastvparsergetval(tvp)); 558 break;
572 jastvparserdestroy(tvp); 573 if (!cmpt->sampperx || !cmpt->samppery) { 574 goto error; 575 } 576 if (mifhdraddcmpt(hdr, hdr->numcmpts, cmpt)) { 577 goto error; 578 } 579 return 0; 580 581 error: 582 if (cmpt) { 583 mifcmptdestroy(cmpt); 584 } 585 if (tvp) { 586 jastvparserdestroy(tvp); 587 } 588 return -1;
Both tvp and tvp->buf are freed by jastvparserdestroy(tvp), but if one of the two following branch conditions is taken, a second call to jastvparserdestroy(tvp) occurs. It is a use-after-free because before calling free in jastvparserdestroy there is a check to tvp->buf, while tvp could have been freed. Two double free take place just after this check (on tvp->buf and tvp).

The REPL server (--listen) in GNU Guile 2.0.12 allows an attacker to execute arbitrary code via an HTTP inter-protocol attack.
The mkdir procedure of GNU Guile temporarily changed the process' umask to zero. During that time window, in a multithreaded application, other threads could end up creating files with insecure permissions. For example, mkdir without the optional mode argument would create directories as 0777. This is fixed in Guile 2.0.13. Prior versions are affected.

Integer overflow in the mozilla::layers::BufferTextureClient::AllocateForSurface function in Mozilla Firefox before 43.0 and Firefox ESR 38.x before 38.5 allows remote attackers to execute arbitrary code by triggering a graphics operation that requires a large texture allocation.
Integer underflow in the RTPReceiverVideo::ParseRtpPacket function in Mozilla Firefox before 43.0 and Firefox ESR 38.x before 38.5 might allow remote attackers to obtain sensitive information, cause a denial of service, or possibly have unspecified other impact by triggering a crafted WebRTC RTP packet.
Integer underflow in the Metadata::setData function in MetaData.cpp in libstagefright in Mozilla Firefox before 43.0 and Firefox ESR 38.x before 38.5 allows remote attackers to execute arbitrary code or cause a denial of service (incorrect memory allocation and application crash) via an MP4 video file with crafted covr metadata that triggers a buffer overflow.
Use-after-free vulnerability in Mozilla Firefox before 43.0 and Firefox ESR 38.x before 38.5 allows remote attackers to execute arbitrary code by triggering attempted use of a data channel that has been closed by a WebRTC function.
Integer overflow in the MPEG4Extractor::readMetaData function in MPEG4Extractor.cpp in libstagefright in Mozilla Firefox before 43.0 and Firefox ESR 38.x before 38.5 on 64-bit platforms allows remote attackers to execute arbitrary code via a crafted MP4 video file that triggers a buffer overflow.
Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 43.0 and Firefox ESR 38.x before 38.5 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.
The directrun function in directmachine.cpp in Libgraphite in Graphite 2 1.2.4, as used in Mozilla Firefox before 43.0 and Firefox ESR 38.x before 38.6.1, does not validate a certain skip operation, which allows remote attackers to execute arbitrary code, obtain sensitive information, or cause a denial of service (out-of-bounds read and application crash) via a crafted Graphite smart font.
Code.cpp in Libgraphite in Graphite 2 1.2.4, as used in Mozilla Firefox before 43.0 and Firefox ESR 38.x before 38.6.1, does not consider recursive load calls during a size check, which allows remote attackers to cause a denial of service (heap-based buffer overflow) or possibly execute arbitrary code via a crafted Graphite smart font.
The SillMap::readFace function in FeatureMap.cpp in Libgraphite in Graphite 2 1.2.4, as used in Mozilla Firefox before 43.0 and Firefox ESR 38.x before 38.6.1, mishandles a return value, which allows remote attackers to cause a denial of service (missing initialization, NULL pointer dereference, and application crash) via a crafted Graphite smart font.
The TtfUtil:LocaLookup function in TtfUtil.cpp in Libgraphite in Graphite 2 1.2.4, as used in Mozilla Firefox before 43.0 and Firefox ESR 38.x before 38.6.1, incorrectly validates a size value, which allows remote attackers to obtain sensitive information or cause a denial of service (out-of-bounds read and application crash) via a crafted Graphite smart font.
Multiple integer underflows in Grub2 1.98 through 2.02 allow physically proximate attackers to bypass authentication, obtain sensitive information, or cause a denial of service (disk corruption) via backspace characters in the (1) grubusernameget function in grub-core/normal/auth.c or the (2) grubpasswordget function in lib/crypto.c, which trigger an "Off-by-two" or "Out of bounds overwrite" memory error.
The binary delta decoder in Mercurial before 3.7.3 allows remote attackers to execute arbitrary code via a (1) clone, (2) push, or (3) pull command, related to (a) a list sizing rounding error and (b) short records.
Mercurial before 3.7.3 allows remote attackers to execute arbitrary code via a crafted name when converting a Git repository.
Mercurial before 3.7.3 allows remote attackers to execute arbitrary code via a crafted git ext:: URL when cloning a subrepository.
A flaw was found in IPython's notebook handling:
Local folder name was used in HTML templates without escaping, allowing XSS in said pages by carefully crafting folder name and URL to access it.
