(subscribe to this query)

Heap-based buffer overflow in SPICE prior to 0.12.6 allows guest OS users to cause a denial of service (heap-based memory corruption and QEMU-KVM crash) or possibly execute arbitrary code on the host via QXL commands related to the surface_id parameter.

Integer signedness error in the Mac_Read_POST_Resource function in base/ftobjs.c in FreeType prior to 2.5.4 allows remote malicious users to cause a denial of service (heap-based buffer overflow) or possibly have unspecified other impact via a crafted Mac font.

type42/t42parse.c in FreeType prior to 2.5.4 does not consider that scanning can be incomplete without triggering an error, which allows remote malicious users to cause a denial of service (use-after-free) or possibly have unspecified other impact via a crafted Type42 font.

sfnt/ttload.c in FreeType prior to 2.5.4 proceeds with offset+length calculations without restricting the values, which allows remote malicious users to cause a denial of service (integer overflow and out-of-bounds read) or possibly have unspecified other impact via a crafted SFN...

Off-by-one error in the pcf_get_properties function in pcf/pcfread.c in FreeType prior to 2.5.4 allows remote malicious users to cause a denial of service (NULL pointer dereference and application crash) via a crafted PCF file with a 0xffffffff size value that is improperly incre...

bdf/bdflib.c in FreeType prior to 2.5.4 identifies property names by only verifying that an initial substring is present, which allows remote malicious users to discover heap pointer values and bypass the ASLR protection mechanism via a crafted BDF font.

The Mac_Read_POST_Resource function in base/ftobjs.c in FreeType prior to 2.5.4 proceeds with adding to length values without validating the original values, which allows remote malicious users to cause a denial of service (integer overflow and heap-based buffer overflow) or poss...

The tt_face_load_hdmx function in truetype/ttpload.c in FreeType prior to 2.5.4 does not establish a minimum record size, which allows remote malicious users to cause a denial of service (out-of-bounds read) or possibly have unspecified other impact via a crafted TrueType font.

The tt_face_load_kern function in sfnt/ttkern.c in FreeType prior to 2.5.4 enforces an incorrect minimum table length, which allows remote malicious users to cause a denial of service (out-of-bounds read) or possibly have unspecified other impact via a crafted TrueType font.

The _bdf_parse_glyphs function in bdf/bdflib.c in FreeType prior to 2.5.4 does not properly handle a missing ENDCHAR record, which allows remote malicious users to cause a denial of service (NULL pointer dereference) or possibly have unspecified other impact via a crafted BDF fon...
