Integer signedness error in the cmsAllocGamma function in src/cmsgamma.c in Little cms color engine (aka lcms) before 1.17 allows attackers to have an unknown impact via a file containing a certain "number of entries" value, which is interpreted improperly, leading to an allocation of insufficient memory.

Buffer overflow in the ReadEmbeddedTextTag function in src/cmsio1.c in Little cms color engine (aka lcms) before 1.16 allows attackers to have an unknown impact via vectors related to a length parameter inconsistency involving the contents of "the input file," a different vulnerability than CVE-2007-2741.
