Multiple buffer overflows in Gaim 0.75 allow remote attackers to cause a denial of service and possibly execute arbitrary code via (1) octal encoding in yahoodecode that causes a null byte to be written beyond the buffer, (2) octal encoding in yahoodecode that causes a pointer to reference memory beyond the terminating null byte, (3) a quoted printable string to the gaimquotedpdecode MIME decoder that causes a null byte to be written beyond the buffer, and (4) quoted printable encoding in gaimquotedpdecode that causes a pointer to reference memory beyond the terminating null byte.

Multiple "memory alignment errors" in libgadu, as used in ekg before 1.6rc2, Gaim before 1.5.0, and other packages, allows remote attackers to cause a denial of service (bus error) on certain architectures such as SPARC via an incoming message.

The gaimmarkupstriphtml function in Gaim 1.2.0, and possibly earlier versions, allows remote attackers to cause a denial of service (application crash) via a string that contains malformed HTML, which causes an out-of-bounds read.

Gaim 1.2.0 allows remote attackers to cause a denial of service (application crash) via a malformed file transfer request to a Jabber user, which leads to an out-of-bounds read.
