UBUNTU-CVE-2018-20187

A side-channel issue was discovered in Botan before 2.9.0. An attacker capable of precisely measuring the time taken for ECC key generation may be able to derive information about the high bits of the secret key, as the function to derive the public point from the secret scalar uses an unblinded...

FreeBSD : OpenSSL -- ChaCha20-Poly1305 nonce vulnerability (e56f2f7c-410e-11e9-b95c-b499baebfeaf)

The OpenSSL project reports : Low: ChaCha20-Poly1305 with long nonces CVE-2019-1543 ChaCha20-Poly1305 is an AEAD cipher, and requires a unique nonce input for every encryption operation. RFC 7539 specifies that the nonce value IV should be 96 bits 12 bytes. OpenSSL allows a variable nonce length...

The vulnerability of the ReadImage function in the GIMP graphic editor, which involves reading beyond the buffer limit of memory, allows attackers to cause service failures, undermine data integrity, and compromise confidentiality.

The vulnerability of the ReadImage function in the GIMP graphic editor’s plug-ins/common/file-tga.c file is related to the issue of writing out images from memory beyond the buffer boundary when reading RGBA images that contain non-standard pixel bit values. Exploiting this vulnerability can allo...
